Maggie Aderin-Pocock and Chris Lintott look back at some of the biggest stories featured on the programme in 2020, with the help of special guests who have chosen their favourite moments. From the launch of Solar Orbiter to the discovery of phosphine on Venus, the team relive the astronomy highlights of a highly unusual year.

In February 2021, orbiters from China and the UAE settled into their positions above Mars, and Nasa’s Perseverance rover touched down on its surface. Maggie Aderin-Pocock reviews the astonishing footage the rover has already sent back, and talks with its legendary chief designer Adam Seltzer about the challenges of missions to the red planet.

The Gaia space telescope is not just helping scientists create the ultimate star map of the Milky Way. It is also showing our galaxy's past and how it will change in the future.

The Sky at Night team visit the companies spearheading the boom in Britain's space industry, a sector with an annual income of £16.4bn and which employs over 45,000 people.

Chris and Maggie dive into the archives to discover how the hunt for extra-terrestrial life in the universe has been reported by the BBC over six decades.

Juno, Nasa's mission to Jupiter, is still gathering data on the gas giant, a decade after it was launched.

A special ‘Question Time’ edition of the programme. Planetary scientist Carly Howett and cosmologist Hiranya Peiris join the team to answer questions from viewers covering all things astronomical

Sir Patrick Moore (1923-2012) began presenting The Sky at Night in April 1957. Airing a new episode every month, the show continues to explore our solar system and beyond. It is the longest running science show on TV. Many famous people have appeared on The Sky at Night, among them: Harlow Shapley, Carl Sagan and Jocelyn Bell-Burnell. Many astronauts have also appeared, including Neil Armstrong and Buzz Aldrin. Recordings of most of the early episodes no longer exist.

Chris and Maggie look back at some of the stories they have covered in 2021 in the Sky at Night’s big review of the year.

The Sky at Night team go back to basics to show you how to enjoy the night sky, wherever you are. It doesn’t matter if you live in a city or in the countryside, if you have a telescope, a pair of binoculars or just your eyes to look with. Pete explains why the night sky changes and joins a group of novice stargazers to talk about the best ways to introduce newcomers to the night. Chris ventures onto a roof in Oxford and marvels at the moon through binoculars, and Maggie goes back to her childhood telescope-making class to talk basic telescope essentials. Curious about the night sky but don’t know where to start? Want to know how to make the most of your new telescope? This is the programme for you!

The Sky at Night discovers how Esa's solar orbiter was built, and how it will protect itself against the sun's searing heat and investigate its mysteries.

The Sky at Night celebrates its 800th episode by showing how you can still explore space even when confined to your home by the coronavirus lockdown. Plus a new arrangement of the show's theme tune.

The Sky at Night team explore a changing world. Maggie Aderin-Pocock interviews astronaut Jessica Meir, who returned from 205 days on the International Space Station to a world she barely recognised. They also discuss Jessica’s experiments in micro-gravity, growing lettuce in space and the first all-female spacewalk. Chris Lintott meets the astronomer who recently announced the discovery of the closest black hole to Earth. Pete Lawrence photographs the dark side of Venus and Lucie Green investigates whether Elon Musk’s constellation of Starlink satellites are ruining the night sky.

The Sky at Night team explore the life and death of stars, including the dimming of Betelgeuse and the drawings that pre-date the telescope but which can predict solar activity.

Mars has fascinated us ever since we first looked up to the heavens. We have imagined alien civilisations, exotic life forms and even dreamed of travelling there ourselves. But after the first probes flew past the Red Planet, and with each subsequent mission that has orbited or landed on its surface, that vision has changed. We’ve come to realise that the planet is, most likely, dead. But that hasn’t dimmed our hopes for finding evidence of past life. And our desire to travel there and colonise the Red Planet still endures. From the very beginning of this exploration, the BBC has recorded our shifting perception of Mars. Since the Sky at Night started broadcasting in 1957, there have been over 50 episodes devoted to Mars and more than ten episodes of Horizon. This programme looks back at that coverage.

The Sky at Night gains exclusive access to the team of scientists behind the recent discovery of possible signs of life on Venus. Recorded in secret before the news broke, the film reveals the story behind this extraordinary piece of scientific discovery.

The focus for this edition of The Sky at Night is on astronomical research that is beyond the scope of our eyes. We think of astronomy as something we do primarily using our sight. But we can now search the cosmos using radiation beyond the narrow band of visible light, beyond what we are able to see. We visit the UK’s foremost radio observatory, Jodrell Bank, and meet some remarkable, vision-impaired astronomers who are pioneering new techniques to carry out their research using their senses of hearing and touch.

Chris and Maggie report on the reaction to the dramatic announcement of the discovery of phosphine gas in the clouds of Venus, a gas that could be a sign of life. Venus remains an inhospitable and unlikely host. But if not Venus, where in the solar system is the best place to look for alien life? Chris and Maggie investigate the latest missions to Mars and the icy moons of Jupiter and Saturn. Away from the search for life, Pete previews the best meteor showers of the year.

The Sky at Night looks back at the last ten years of astronomy and ponders the most significant milestones and revelations. With the help of six distinguished astronomers, Chris and Maggie consider the state of astronomy in 2020 and wonder what new, exciting discoveries await us across the rest of the decade, as a host of new ground and space telescopes come online. Astronomer Royal Lord Martin Rees is among the guests to walk along the Astronomical Wall of Discovery in this one-hour special.

On 1 January 2019, Nasa's New Horizons probe notched up another historic first: the first ever Kuiper belt fly-by. Its target was 2014 MU69, a chunk of ice and rock about four billion miles (approximately 6.4 billion kilometres) from Earth, dubbed Ultima Thule, a Latin phrase meaning a distant, unknown region. It is the most distant fly-by in history, and it is believed the data New Horizons gathers will shed new light on the solar system's early days. Chris Lintott reports from the John Hopkins Applied Physics Laboratory in Maryland to bring the latest news and pictures from this extraordinary mission.

Ever since we discovered that distant galaxies are racing away from us, there has been a heated debate over just how fast the Universe is expanding. At the beginning of the 21st century, we thought we knew the answer. But now, two very different viewpoints have emerged. And they are dividing the scientific community. The Sky at Night meets leading astronomers and cosmologists on both sides of the debate. Which team has the right answer? Or could both teams be right? If so, we may need to rethink everything we think we know about the Universe.

Marsquake! This month's episode follows Insight, NASA’s latest mission to the Red Planet, as it goes in search of the secrets buried deep below Mars’s surface. By listening for tremors caused by Marsquakes and meteor strikes, scientists hope to reveal how the planet was formed, why its fate was so different from the Earth and whether the planet is dead or alive. The programme also says a heartfelt goodbye to Opportunity, the rover that explored the surface of Mars for more than 14 years until it was engulfed by a dust storm last year.

The team reveals how the first picture of a supermassive black hole was captured. The photograph of the hole at the heart of the M87 galaxy was released in April.

In the first of two programmes to commemorate the 50th anniversary of the Apollo Moon landings, the Sky at Night team take a look at the latest plans to return to the Moon. Recently, China, Israel and India have all sent major missions to the Moon. The Europeans and Americans are planning to build a space station in permanent orbit around the Moon. And NASA has just announced that they plan to land astronauts on the Moon’s surface within five years. It all suggests that we are on the verge of a new golden age in lunar exploration.

To celebrate the 50th anniversary of the Apollo mission to put a man on the moon, The Sky at Night looks back through the archives to tell the story of how the BBC reported the moonshot, with some very special guests. Scientist John Zarneki discusses the huge scientific and engineering challenge. The first British astronaut, Helen Sharman, reveals just how accurate the predictions and preparations for life in space were. And writer and broadcaster James Burke - who reported the whole amazing story at the time - explains why Nasa loved the BBC and how he gained access to the command module for an episode of Tomorrow’s World.

The programme goes behind the scenes as the European Space Agency selects its next mission, which will be launched in 2028, meeting British teams vying to have their ideas selected, including a revolutionary mission to a comet.

Astronomers have found more than 4,000 planets circling stars other than our own. What do we know about these alien worlds and how have we managed to detect them?

A one-hour special in which The Sky at Night team face a live studio audience to answer their questions about the mysteries and wonders of the universe.

The Rosetta mission to comet 67P was the first time a spacecraft landed on a comet's surface. What has this icy body taught us about the dawn of the solar system and the origins of life on earth?

Looking back on the major stories of the year - from the New Horizons mission to the most distant world we have ever visited to the release of the first-ever picture of a black hole. The team relive the highlights and uncover the latest developments.

The team reports on unnerving discoveries in the field of space science. Researchers estimate that 95 per cent of everything in the universe is "invisible", and while some of this number is made up of matter that just cannot be easily seen, the rest is thought to be comprised of nebulous concepts such as Dark Matter and Dark Energy. The team illustrates - as best they can - how the existence of these two hypothetical ideas - or lack thereof - could define the fate of the entire universe.

The team investigates an astronomical detective story. In October 2017, astronomers spotted the first ever object to visit our solar system from outer space. They called it 'Oumuamua. Its discovery set off a hurricane of press speculation and a major scientific investigation. The Sky at Night goes to Queen's University in Belfast, which has become the centre of scientific research on this cosmic visitor. When they first spotted it, all scientists knew was that it was small, it was travelling fast, and it came from outside our solar system. What did it look like? How had it formed? What was it made of? Where had it come from? To answer these questions, the team pieces together all the clues that scientists have extracted from the small amounts of data collected as 'Oumuamua flashed through the solar system.

Chris Lintott and Maggie Aderin-Pocock reveal the latest results from NASA's Curiosity and ESA's ExoMars TGO missions that are attempting to find signs of life on Mars. Andy Weir, author of The Martian, shares his thoughts on the possibility of a manned mission.

Maggie Aderin-Pocock and Chris Lintott examine the new information about the Milky Way recorded by the ESA's Gaia space telescope over the past three and a half years, including new data on how stars move over time and how the galaxy was originally formed.

Nasa's Juno spacecraft is currently making its 13th orbit of Jupiter on one of the most ambitious and risky space missions ever undertaken. The astonishing images it has captured are not just visually stunning, they also deliver spectacular scientific insight, revolutionising our ideas about Jupiter. Maggie Aderin-Pocock explores these stunning discoveries, from a new understanding of Jupiter's core and formation to revelations about how deep its raging storms penetrate the planet's mysterious interior.

Chris Lintott travels to the Murchison Radio-astronomy Observatory in Australia to find out how astronomers detected signals from the oldest stars in existence and what this discovery can reveal about the formation of the universe. In February 2018, news broke that astronomers had seen the cosmic dawn - the moment when stars first formed, flooding the universe with light. What's remarkable is that this incredible event was discovered by an instrument the size of a ping-pong table in a remote corner of Western Australia.

One evening in early September 1859, a spectacular blood-red aurora borealis appeared across America. Earlier that same day, in a leafy garden in the UK, a gentleman astronomer had noted a 'white light flare' on the sun's surface. The two events were linked; it's now known that the flare caused the aurora. The flare was a particularly violent eruption from the sun's surface known as a CME, a coronal mass ejection. Back then, it was considered an astronomical curiosity. But when it happens again, it will be a different story. For the modern, technological world such a violent solar phenomenon could be devastating. This episode examines just how damaging a CME could be and how astronomers, using two new satellites that will travel closer to the sun than ever before, can better prepare us for its impact.

A look at two missions attempting one of the most difficult feats of space exploration - to collect a rock from another world. This episode checks in on the US and Japanese attempts to bring a piece of an asteroid back to Earth. The missions have taken decades of planning, but the results will be worth it. We find out how studying these space rocks can teach us about the origins of our solar system and may one day help save Earth from a catastrophic collision.

The future of Britain's space programme, examining plans for the first UK spaceport in Scotland and the development of a new rocket system. The programme also examines a revolutionary new form of micro-satellites, and the plans to potentially launch thousands of them worldwide. Plus, Tim Peake takes a look at the history of British space exploration.

A report on BepiColombo, a spacecraft sent on a seven-year journey to the heart of the solar system to study Mercury. The objective is to discover why the smallest planet in the solar system seems to be shrinking even further, how it survives orbiting so close to the sun, and how it was formed in the first place.

Chris Lintott visits an observatory aboard a jumbo jet, which carries an infra-red telescope able to observe space from the vantage point of 40,000 feet above sea level. Plus, a look at how planets form and why fewer newly formed stars are being recorded.

All good travel guides need a map, and the team unveil the most detailed 3D map of the Milky Way ever produced. A map that reveals that there may be 50 per cent more stars in the galaxy than we previously thought. American astronomer Neil deGrasse Tyson gives us a guided tour of the strangest stars we have ever observed, and we discover that the Milky Way may already be colliding with our neighbouring galaxy, Andromeda.

The team travel to the island of La Palma in the Canary Islands where they take control of some of the world's largest telescopes to view the most spectacular sights in the night sky.

When the first episode of The Sky at Night was transmitted in April 1957, it was still thought that Mars could be home to advanced life, the Space Age was yet to begin, and the Big Bang was just a controversial theory. So to celebrate its 60th anniversary, this special programme looks at how our knowledge of the universe has been transformed in the last six decades - from the exploration of the solar system to the detection of black holes and planets orbiting distant stars. Featuring contributions from Jim Al-Khalili, Dallas Campbell and Monica Grady and including special birthday messages from a host of stars, this is a celebration of an extraordinary age of discovery, and The Sky at Night's role in covering it.

This edition comes from the heart of one of the most influential - and surprising - organisations in the history of astronomy. Maggie and Chris have been granted rare access to the Vatican and its little-known observatory, the Specola Vaticana, perched on a hilltop 30km outside Rome. -- There they explore its rich history and contemporary cutting-edge science, going inside the Vatican walls to visit the Tower of the Winds, a secret antique sundial that revolutionised the length of the year; the remains of a nest of telescopes atop an old medieval church where the science of spectroscopy was born; and the modern labs, manned by priest scientists who study a range of contemporary astronomical problems, from meteorites to binary stars to the birth of the universe itself.

The team looks at the trans-Neptunian objects - a vast number of strange, dark, icy worlds - which played a crucial role in the evolution of our solar system.

In August, the most spectacular meteor shower of 2017 coincides with transmission: The Perseids! If it's clear, it'll be a great chance to see scores of bright shooting stars streaking across the night sky. As those shooting stars vaporise in the atmosphere, a small part of some of them will fall to earth as dust. This dust will contribute to a total of about 40,000 tonnes of space dust and debris that falls onto our planet every year. In this episode, Chris Lintott and Maggie Aderin-Pocock investigate this mysterious cosmic debris that comes from outer space.

On 15 September 2017, the most successful space mission of all time will come to a dramatic and violent end as the Cassini probe is sent crashing into the planet Saturn. This one space probe has rewritten the rules of space exploration, repeatedly surprising scientists with its incredible and unexpected observations. It discovered lakes of pure methane on Saturn's moon Titan, mysterious weather systems on Saturn itself, and all the conditions for life on the moon Enceladus. It has exceeded every expectation of its original design brief, and its mission duration has been extended not once but four times. Its legacy for science and for space travel is unique. Chris Lintott and Maggie Aderin-Pocock explore four major ways in which space exploration of the future has been changed by the discoveries of the Cassini mission.

A look at the reasons behind renewed interest in sending manned missions to the moon, with plans by technology companies to build a permanent base on the satellite.

Observing events that occur in milliseconds, including the recently detected gravitational wave created by the collision of two neutron stars. Chris Lintott joins astronomers trying to detect a gamma ray burst in space, while Lucie Green discovers how similar phenomena can be found much closer to home. We're used to thinking that the universe operates on timescales of millions or even billions of years, where change happens with imperceptible slowness. But now we've discovered a whole catalogue of events that happen over much shorter times - seconds or even milliseconds. And these sudden, transient occurrences are among the most mysterious, powerful and destructive events in the universe. Observing them has raised exciting new questions about the way the universe works. This month The Sky at Night explores this world of transient phenomena. We hear more about the explosive event that created the recently detected gravitational wave - the collision of two neutron stars. And Chris spends 24 hours at the SWIFT space telescope base in Leicester in an attempt to detect a gamma ray burst - the most powerful and extreme short-term event known. Maggie goes to meet the team that are searching for the mysterious, barely understood transient phenomena called fast radio bursts. And Lucie Green reveals that some important short-term phenomena can occur much closer to home too. Astronomy used to be about staring up at the unchanging sky, so this search for transitory objects is truly revolutionary. It's time to enter the spectacular world of astronomy that takes place... in the blink of an eye...

The Sky at Night celebrates one of the most profound, moving and enjoyable activities there is - the ancient art of looking up, studying and marvelling at the night sky. The programme is based at the Royal Observatory, Greenwich - the spiritual home of British astronomy - and sets out to discover the many and varied ways we can all enjoy the majesty of the skies. Maggie Aderin-Pocock travels to Norway to see the northern lights, and discovers that we are in a golden age of aurora research as she learns what they tell us about the solar system. Chris Lintott learns the ancient art of navigating by the stars, whilst Pete Lawrence helps choose the right equipment to set yourself up as an amateur astronomer. This is your guide to observing and enjoying all the Wonders of the Night Sky.

On January 20 2016, two American astronomers made an extraordinary claim - they had found evidence for a ninth planet in our solar system, a planet 20 times further out than Neptune which would take up to 20,000 years to orbit the sun. It is a discovery that could completely rewrite our understanding of our solar system and how it formed. As the world's biggest telescopes start scanning the skies searching for Planet 9, the Sky at Night team investigates. If Planet 9 exists, where is it and where did it come from? In California, Chris Lintott meets the astronomers whose study of the distant Kuiper Belt led them to predict the existence of the planet. And while some scientists are still sceptical, Maggie Aderin-Pocock discovers how our models of the formation of the solar system and the discovery of similar exoplanets around other stars all support the existence of Planet 9.

For 50 years we have been sending probes to gather close-up images of the other planets and moons of the solar system. The Sky at Night presents the five greatest images captured by those spacecraft. From a view of the surface of Mars, to live pictures of the sun and a unique picture of our own planet, these are the images that have transformed our perception of the solar system we live in.

Chris Lintott and Maggie Aderin-Pocock present a look at black holes, featuring an exclusive interview with Stephen Hawking. The physicist discusses how the recent detection of gravitational waves has added to scientific understanding of black holes, and may prove his own theories explaining how they can have properties that defy all known laws of physics. The programme looks at the latest understanding of black holes, featuring an interview with Stephen Hawking. Black holes are one of the greatest mysteries in the universe. They behave in a way that is contrary to laws of physics and one has never actually been seen. However, the recent detection of gravitational waves, as predicted by Einstein, proves that black holes exist and provides a way to investigate their remarkable behaviour and properties.

May 9 2016 sees one of the astronomical highlights of the year - a transit of Mercury across the sun, the best opportunity to observe this phenomenon until 2049. To mark the event, the Sky at Night attempts to explain the many mysteries of Mercury - a planet so bizarre that it is sometimes described as the 'problem child' of the solar system. Surface temperatures exceed 450 degrees but it also has patches of ice, its day is twice as long as its year, and it is a planet that appears to be shrinking.

Chris Lintott and Maggie Aderin-Pocock report on a plan to train as many telescopes as possible on the Whirlpool Galaxy. This star formation is 30 million light years from Earth and was discovered in 1773, its spiral shape believed to have been the inspiration for Van Gogh's painting Starry Starry Night. Optical and infra-red telescopes, radio observatories and ultraviolet and x-ray sensors will study the galaxy to learn more about a wave of intense star formation.

A look behind the scenes of Nasa's project to study Jupiter. As the spacecraft Juno enters Jupiter's orbit, the programme explores the dangers of the mission and what Nasa is hoping to discover about the giant planet - from the secrets of its formation to the source of the solar system's most powerful aurora.

Chris Lintott and Maggie Aderin-Pocock report on the recent discovery of a planet with similar qualities to Earth orbiting Proxima Centauri, the nearest star to our solar system. The programme examines what the environment of this world might be like and the logistics of building a spacecraft capable of travelling 4.23 light years to reach it.

Chris Lintott and Maggie Aderin-Pocock report on the Rosetta spacecraft as it prepares to crash into the surface of comet 67P Churyumov-Gerasimenko. This month the Sky at Night goes behind the scenes at the European Space Agency as the Rosetta mission reaches its dramatic conclusion and the spacecraft is crashed into the surface of comet 67P Churyumov-Gerasimenko. For nearly two years the Rosetta spacecraft has been in orbit around 67P - studying the comet at close range and returning the most extraordinary pictures. But now the the mission must come to an end and the project scientists have decided to have one final attempt at studying the comet at closer range than ever before. On September 30th the spacecraft - with all its instruments running - will be crashed into the surface of the comet. Its aim is to get the best ever view of the mysterious pits on the comet's surface. Pits whose walls are thought to have been undisturbed for over 4 billion years, since the formation of the solar system. Chris Lintott will be in mission control with the scientists as they watch the pictures come in from the spacecraft's dive towards the surface. And Maggie Aderin-Pocock will be investigating how the mission has transformed our understanding of comets and the birth of the solar system.

The Sky at Night team investigates the ongoing hunt for life on Mars. It is one of the great scientific questions of our time, but are we any closer to finding an answer? As well as uncovering the cause of the recent crash of the Schiaparelli lander, the team looks at the next missions designed to hunt for life on the red planet - from a rover designed to drill deep into the surface, to the orbiter sniffing for signs of methane in the atmosphere. Adam Rutherford joins the team to ask if we have been deliberately avoiding the most likely places to find life on Mars.

Maggie Aderin-Pocock and Chris Lintott present a look back at some of the biggest stories in space science of 2016, and see how these discoveries have developed since making the headlines. Featuring a look at new evidence of a ninth planet in the solar system, the Juno probe's study of Jupiter, and scientists searching for evidence of other planets capable of sustaining human life.

The Milky Way, our galaxy, is a magnificent sight in the night sky, but we know surprisingly little about it for certain. What is its shape? How many stars does it actually contain? What lies at its centre? The Gaia space telescope will answer these questions, being armed with the most advanced camera to leave our planet, and it will allow us to see our galaxy as we've never seen it before. The Sky at Night visits the factory in Chelmsford that made the astonishing sensor at the heart of the mission.

From unexplained flashes in the night sky to flying saucers, this episode delves into the mysterious world of UFOs. How our drive to explain these bizarre phenomena, and desire to discover little green men, has in fact transformed our understanding of the universe.

For 25 years the Hubble Space Telescope has been showing us the cosmos as we've never seen it before. The team reveals the 'top five' greatest images Hubble has produced, images that have astounded us, transforming our understanding of the universe and our place in it.

The team explores our nearest neighbour Venus, discovering how it formed and how ESA's Venus Express spacecraft has revealed the secrets of its atmosphere. -- How can two such similar planets have become so different? One is the crucible of life, the other an inferno with a surface scorched by raining acid, yet both began as almost identical bodies. With Venus prominent in the sky in May, the team explores our nearest neighbour, discovering how it formed and how ESA's Venus Express spacecraft has revealed the secrets of its atmosphere.

With the exciting news that the Philae lander had woken up on comet 67P, Sky at Night reveals the latest results from the Rosetta comet landing. What have they learnt so far from Philae's onboard instruments? What do the stunning images from Rosetta tell us about the formation and structure of comets? And project scientist Matt Taylor shows how Rosetta is measuring the growing tail of the comet as it hurtles towards the sun.

Maggie Aderin-Pocock and Chris Lintott present the inside story of NASA's groundbreaking visit to Pluto. This is the first time any probe has visited the dwarf planet and Sky at Night has ringside seats, bringing you the entire story and expert insight into the latest images from the New Horizons probe. Sky at Night celebrates its 750th episode with the most exciting space event of 2015.

The Sky at Night team look at cosmic explosions. They explore the beautiful but potentially deadly outbursts of our very own star - the sun - and the most violent and energetic events in the universe, gamma ray bursts.

The team looks at the dynamic nature of the universe, winding its timeline backwards and forwards to reveal how the night sky changes over time. We see how different the night sky looked in the past and how it will be transformed billions of years into the future as the stars migrate and galaxies collide. Broadcast from the Royal Observatory Greenwich, the team explores the latest theories on solar system evolution - how the familiar layout of today's solar system was created by a gravitational dance between the giant planets that left scars we can still see today.

We think of volcanoes as some of the most powerful natural phenomena on earth - but they are nothing compared to the volcanoes we find elsewhere in the solar system. This month's Sky at Night reveals the weird and wonderful world of volcanism on other planets and moons - from the giant extinct volcanoes of Mars to the tantalising possibility of continuing eruptions on Venus, and from the vast sulphur plumes of Io to the mysterious cryovolcanoes of Enceladus.

As we close in on the discovery of the 2,000th planet outside our solar system, or exoplanet, the Sky at Night investigates the techniques that are revealing so much about these alien worlds. The programme asks if we are really any closer to finding another world like our own - a second Earth.

Astronomers have been fascinated by the idea of the Star of Bethlehem for centuries. Did it exist? And if so, what was it? The list of candidates includes some of the most exciting objects in the night sky - supernovae, comets, meteors and unusual alignments of the giant planets. In this surprising and entertaining Christmas special the Sky at Night team go in search of the potential causes of the Star of Bethlehem. The team explore the possibilities, investigating the nature of the phenomena and digging through the historical records including Babylonian clay tablets and ancient Chinese manuscripts, to reconstruct events in the night sky 2,000 years ago. Maggie Aderin-Pocock goes hunting for supernovae using the most powerful laser in Britain, and discovers that these mighty explosions caused by the death of stars can shine brighter than the moon in our sky. Chris Lintott reconstructs the night sky over Jerusalem at the time of Jesus's birth, discovering a once-in-a-millennium conjunction of Saturn and Jupiter that was first suggested as a cause of the star by the great astronomer Johannes Kepler in 1604. Armed with his telescope, Pete Lawrence searches out the features of the night sky we can observe today that may provide clues to the origin of the Star of Bethlehem. Professor Alan Fitzsimmons explains why the sudden appearance of a comet in the night sky has always been seen as an omen of great events on Earth. Dallas Campbell goes in search of the historical and archaeological records that can shed light on the identity of the star. Finding Babylonian tablets in the vaults of the British Museum and ancient Chinese texts that record all the unusual events in the night sky 2,000 years ago, including a bright new star that appeared for 70 days in the year 5BC.

The revamped team look at Jupiter's coloured bands and iconic 'eye', visible manifestations of a violent atmosphere that causes extraordinary weather.

The Sky at Night team listens to the sounds of the cosmos. Maggie Aderin-Pocock and Chris Lintott explore how sound can reveal extraordinary secrets about the universe - from orchestral tunes rippling on the surface of the sun and the crackle of Jupiter's atmosphere to the sound waves that reveal how the universe was formed. This is astronomy as you've never heard it before.

Mars captures the imagination like no other planet and currently our nearest neighbour is at its brightest for several years, so it's a perfect opportunity to explore a planet that is tantalisingly similar to our own. And in the past it may have been even more like Earth, an inviting and habitable place, a perfect environment for life to flourish. Geologist Iain Stewart investigates how we can read the story of Mars's extraordinary past from its rocks, Maggie Aderin-Pocock comes face to face with the latest Mars rover and Chris Lintott meets the man behind the discovery which the whole history of the universe now rests upon.

The universe is filled with spectacular objects, from gloriously-coloured nebulae to the swirling motion of a billion stars formed into a single galaxy. One force has created it all - gravity. The Sky at Night team steps away from the bright lights and travels to the Brecon Beacons AstroCamp to see how gravity shapes the universe, in all its spectacular glory. Maggie Aderin-Pocock asks why so much of the night sky is filled with spheres and why not all these spheres are what they seem. Chris Lintott finds out about the newest moon in the solar system that has just formed in Saturn's rings, and how it could shed light on how the planets formed billions of years ago. Plus, how to get great images of the night sky without using a telescope and what the shape of a galaxy tells you about its past.

The team looks at the cosmic impacts which have shaped the universe around us, from asteroids crashing into the surface of the moon to galaxies colliding with each other.

The team explore stargazing in the daytime, show how seasons change on other planets across the solar system and examine what makes the sun special.

The team goes behind the scenes at mission control for the critical point of the most ambitious space project of the decade. The European Space Agency's Rosetta probe finally catches up with the comet it has been chasing across the solar system for ten years and prepares to send out a lander armed with drills and harpoons for a daredevil attempt to hitch a ride. With the latest images revealing that it may even be two comets stuck together, Dr Chris Lintott is on hand in Germany with updates from the mission team on this unparalleled challenge, whilst Dr Maggie Aderin- Pocock reveals the instruments that the lander is carrying.

Are we alone? Geneticist Dr Adam Rutherford seeks to define what life is and Maggie Aderin-Pocock explores our chances of finding it in the universe.

The vast frozen worlds of Uranus and Neptune are the most enigmatic and mysterious planets in the solar system. From the most powerful winds ever recorded to their exotic atmospheres, what makes these planets so unique? Chris Lintott and Maggie Aderin-Pocock reveal the latest images of the ice giants, while award-winning astro-photographer Damian Peach shares his tips for capturing these jewels of the night sky.

It is one of the most extraordinary space adventures in a generation - to land a spacecraft on a comet. The European Space Agency's (ESA) Rosetta spacecraft has been hurtling through space for over 10 years, tracking down a comet called 67P/Churyumov-Gerasimenko. Now it is about to do something that has never been attempted before and land a spacecraft on the comet's surface. This special episode of The Sky at Night puts the viewer right at the heart of the action, witnessing events as they happened from inside mission control. It reveals the latest images, explores the first groundbreaking science coming back from the comet and asks the astonishing questions that make this mission so captivating. Could Earth's water have come from comets? How do comets survive for so long? Could they have triggered the start of life on Earth? The journey has been fraught with risk and at every stage the comet seems to surprise, but if the mission succeeds it will be a momentous day in the history of space exploration.

Perhaps no object in the night sky conjures up a greater sense of awe and wonder than a nebula. These vast clouds of dust and gases are stupendously beautiful, but they aren't just pretty objects. Nebulae play a key role in the birth and death of stars, and therefore in our own origins. And driving their creation is a kind of chemistry that the textbooks say shouldn't be happening.

For more than half a century Sir Patrick Moore encouraged people to look up at the wonders of the night skies. Fittingly in this programme, recorded just before his death, he and his team offer advice to those who are discovering astronomy for the very first time. How should they set up their new telescopes and what should they seek out in the winter skies as they begin to share Sir Patrick's lifelong passion for the stars?

The team are at the Royal Observatory, Greenwich, to see how the sun affects our planet.

There are amazing astronomical objects to see in the winter night sky, and Sir Patrick Moore chose a few of them for his last Moore Winter Marathon. To find out how everyone got on, Chris Lintott and Lucie Green travel to the Kielder observatory in Northumberland to enjoy some of the darkest skies in Britain. Jon Culshaw joins them to take part in Patrick's final challenge, and the rest of the team set up their telescopes to try to catch an asteroid which is about to whizz past the Earth, closer than any before.

Meteorites regularly hit Earth, although most go undetected. Occasionally a big meteorite collides with Earth and when it does, it can cause devastation. Lucie Green and Chris Lintott visit the Natural History Museum to look at its meteorite collection and discuss the recent Russian impact. Jon Culshaw goes on a meteorite hunt, while Pete Lawrence and Paul Abel give their beginners' guide on how to look at Saturn.

Saturn is in our evening skies, and in any telescope looks a stunner. Lucie Green and Chris Lintott investigate the storm that is still raging in the planet's atmosphere, with the latest news from Saturn's amazing moons Titan and Enceladus. Pete Lawrence and Paul Abel illustrate Saturn's 'opposition effect' and look at some globular clusters, whilst Chris North gets a preview of the new eye-in-the-sky camera, soon to be fitted onto the International Space Station, which will image Earth in incredible detail.

Stars are full of variety - they can be big or little, bright or dim. Our sun is right in the middle - Mr Average - but eventually it will grow old and become a red giant. Lucie Green and Chris Lintott discuss the lives of stars and what happens to them when they die.

Every year thousands flock to Stonehenge to celebrate the summer solstice. Seeing the rise of the summer sun at Stonehenge is one of the most obvious connections between ancient man and the celestial calendar, but there is still fierce debate about possible links between this ancient site and the moon and stars. The team join in the solstice revelry and also launch the Moore Moon Marathon, with some easy things to look at on the moon over summer.

It's a golden era of exploration on Mars, with Nasa's space rover Curiosity finding out new and exciting things about the planet and which might offer the best chance of life elsewhere in our solar system. The spacecraft Mars Express is also celebrating a decade at the red planet and Chris Lintott and Lucie Green pick out some of the highlights, including the 'face of Mars'. Meanwhile Jon Culshaw explores the Moore Moon Marathon with astronomers in Chipping Norton.

Black holes are the beating heart of galaxies. It seems that they are pivotal in their evolution, but they also have a destructive side. A dust cloud more massive than the size of the Earth is on a doomed course, as it careers towards the black hole at the centre of our galaxy. Chris Lintott talks to the Astronomer Royal about this cataclysmic encounter.

The team go camping at the Brecon Beacons star party and answer problems and queries about what to see in the night sky and how to use a telescope. Viewers have been sending in astronomy questions in the hundreds since the Space Surgery was launched six months ago.

The moon is a most familiar sight in our sky - it is the astronomer's friend and was Sir Patrick Moore's favourite object - yet fundamentally we still do not know how it was formed and why its far side looks so different. The team join astronomers on Blackheath to watch a lunar eclipse; find out how everyone got in the Moore Moon Marathon, the list of fascinating features you can see on the moon; and discuss the new missions that will explore this reassuringly familiar yet still most mysterious of cosmic satellites

Astronomers always get excited about comets and in December they are looking forward to something rather special. The snappily-named Comet C/2012 S1 ISON has travelled from the very edges of our solar system on a one way ticket around the sun. As it heats up there is intense speculation about whether it will develop a beautiful tail or just break apart. On the Canary island of La Palma the team use both the Liverpool and Issac Newton telescopes to go comet chasing.

We now know there are other solar systems far away in space, but are they like ours and is there life on these strange worlds? Sir Patrick Moore goes on the quest for little green men.

Space telescopes such as Herschel and Spitzer are peering at the dusty, dark cosmos and with their infrared eyes they can see the cold parts of the sky where stars are being born. Sir Patrick Moore discusses why the infrared is full of hidden delights, whilst Dr Chris North talks to Dr Amy Mainzer about NASA's infrared WISE telescope.

A look at how amateur astronomers can help in the quest for knowledge of the cosmos.

Have you ever dreamed of travelling through space? Sir Patrick Moore takes us on an epic journey to the ends of our known universe, stopping en-route to take in the view. The team engage the warp drive and celebrate 55 years of The Sky at Night - at the speed of light.

The Sky at Night celebrates 55 years with the second of its special programmes. Sir Patrick picked out 55 objects in the April sky and asked viewers to take part in his Moore Marathon. He finds out how everyone got on, with help from the team.

A European mission called JUICE has been announced which will visit Jupiter and its fascinating moons Europa, Callisto and Ganymede. Sir Patrick Moore finds out why these icy moons may harbour conditions suitable for life, and also has the latest news from the Cassini mission, currently sending back astounding images from Saturn.

The Sky at Night travels to the Arctic Circle and the archipelago of Svalbard to see the transit of Venus. This astronomical wonder, where the planet Venus passes in front of the sun, is the last one in our lifetime, but as ever the clouds test the team's nerves.

Up and down the country amateur astronomers are out in their back-garden observatories looking at stars, galaxies and nebulae. The team visits some astronomers on their own turf, to find out what keeps them up late at night.

The NASA rover, Curiosity, the size of a small car and nuclear-powered, landed on Mars in August and took its first view of the red planet. This ambitious mission hopes to find the building blocks of life as well as study the Martian climate and geology. Sir Patrick Moore discusses what Curiosity will be doing, as well as what to see in the September night sky.

Sir Patrick Moore selects celestial objects to observe in the winter night sky and challenges viewers to spot as many as possible. In the second part of the year's Moore Marathon, Sir Patrick has selected two lists to suit astronomers of all abilities - objects that can be seen with the naked eye or binoculars, and more remote ones observable only by telescope.

Sir Patrick Moore, Dr Chris Lintott and Dr Chris North find out what the universe is made of, from the 'dark matter' that shapes our galaxies to the infinitesimally small particles that make up atoms. Pete Lawrence and Paul Abel show how to use a planisphere as a guide to the night sky and what objects can be ticked off on the 'Moore Winter Marathon'.

The tiny planet Mercury is in the morning sky and Sir Patrick Moore talks about the latest news from Messenger, the spacecraft which is over Mercury at the moment. Mercury is often compared to the moon, which was last visited by man in December 1972. Forty years on, Dr Chris Lintott looks at the legacy of that mission, Apollo 17, and what it has been able to tell us about the moon.

The planets and moons of our solar system are covered in volcanoes, some billions of years old and seven times the height of Mount Everest. Sir Patrick Moore discovers the havoc that volcanoes can wreak on our own planet, as well as elsewhere in our solar system.

The great winter constellation of Orion is easily visible, with its ruby red star Betelgeuse and distinctive shape. It is also home to the Orion nebula, our nearest stellar nursery, where thousands of stars are being born. Sir Patrick Moore and the Sky at Night team take us on a tour of this magnificent constellation and its jewels.

Sir Patrick Moore celebrates the 700th episode of The Sky at Night at his home in Sussex, with the help of special guests Professor Brian Cox, impressionist and amateur astronomer Jon Culshaw and Lord Martin Rees, the Astronomer Royal. A stellar panel of astronomers gathers to answer vexing questions from the viewers, while Sir Patrick has a close encounter with his younger self.

Sir Patrick Moore joins an unlikely star party in the heart of London, where enthusiastic astronomers are cutting through the light pollution to see the planets and stars. Dr Chris Lintott also drops in on another star party - the 88th birthday celebrations for the nation's most famous astronomer.

In the atmosphere of Saturn there is a gigantic storm, which is bigger than Earth itself. This month Sir Patrick Moore looks at the ringed planet, which can be seen in our night sky now. He talks to Paul Abel and Dr Chris North about these violent eruptions in the atmospheres of other worlds. And Jon Culshaw, Dr Lucie Green and Pete Lawrence travel to north Norway in search of the aurora borealis.

The summer constellation of Cygnus will soon be flying overhead in our night sky. With its rich array of nebulae and star clusters, it is a delight for astronomers to look at in the warm summer evenings. Sir Patrick Moore looks at the yellow star Albireo with its superb azure blue companion, while Chris North goes in search of the Milky Way.

Sir Patrick Moore visits the South Downs Planetarium and discovers how the stars appeared to the ancient Egyptians, whilst Pete Lawrence explains what to look out for in the summer night sky.

The NASA spacecraft Dawn is getting up close and personal with the asteroid Vesta. Sir Patrick Moore discusses the first fly-by images of this most unusual asteroid, which will tell us more about how our solar system formed some 4.5 billion years ago. Paul Abel and Pete Lawrence their guide to the August night sky, including the return of the red planet Mars.

The future of manned space flight is entering an uncertain phase, with our once vivid dreams of returning to the Moon and landing on Mars shattered by budget cuts and lack of will.

The outer limits of the solar system are a dark, cold and mysterious place, which only the Voyager spacecraft have visited. Sir Patrick Moore discusses the ice giants Uranus and Neptune, while Chris Lintott has an early Christmas treat - a lost episode of The Sky at Night from 1963 which has been returned to the BBC, in which Arthur C Clarke talks about his vision of bases on the moon and speculates when man will be on Mars.

January provides the perfect opportunity to observe stars, planets and galaxies. Sir Patrick Moore takes us on a tour of the winter sky, looking at twinkling 'variable stars' with Dr John Mason, and at planets and galaxies with Pete Lawrence and Paul Abel. Sir Patrick and Dr Chris Lintott also point out the best objects to observe if you've had a telescope for Christmas.

Mars is the brightest thing in the sky and is at its closest to Earth for the next four years. With NASA announcing that its Martian rover Spirit is to rove no more on the red planet, there is an interview with Prof Steve Squyres, the principal investigator of the Mars Exploration Rover Mission, about the attempts to get it out of the sand dune which ensnared it in May 2009 and the agonising decision to stop the rescue.

Half a century ago, scientists were speculating about the possibility of planets outside our solar system. Since then over 400 such extra-solar planets have been discovered. Is there anything living on them and if so, is it intelligent? Sir Patrick Moore debates the question of life in the universe with today's planet hunters and astrobiologists, while at the Royal Society Dr Chris Lintott searches for evidence of alien life.

We can never see our nearest star at night, only by day. Looking at it directly will blind us - because our nearest star is the Sun. Sir Patrick Moore is joined by the Astronomer Royal for Scotland, Professor John Brown and by Dr Chris Davis. They take us on a tour of the Sun, Earth's primary source of energy and without which life would not exist. Pete Lawrence and Paul Abel demonstrate safe ways to look at the Sun from Sir Patrick's observatory in Sussex.

Saturn is one of the largest planets and the beautiful system of rings surrounding it makes it the most distinctive in the solar system.

Ursa Major, the Great Bear, is a rich source of galaxies, double and variable stars and the Hubble Deep Field, through which we are able to look back 10 billion years in time. Sir Patrick Moore and his astronomical team give an intimate guide to one of the skies' most recognisable constellations.

This first Sky at Night of 2009 is a celebration of the humble (and Hubble) telescope, which is now 400 years old. It all began with Galileo . . . or did it? Patrick Moore furrows his brow over the news that an Englishman may have invented the first. Over the last 50 years Patrick has visited almost all of the worlds large telescopes, and there is some archive footage of some of these visits. Meanwhile, Chris Lintott visits some mighty examples in the USA, and astronaut Jeff Hoffman describes how he repaired the Hubble Space Telescope. Preparations are underway in NASA's watertanks for the next repair/update mission, which NASA hopes to be the last, because the next space telescope, the James Webb Space Telescope is scheduled to succeed it. In a unique visite we get to see how 10m glass mirrors are cast and polished under the Arizona Wildcats Football stadium, and talks about the future of Extremely Large Telescopes.

Dr Chris Lintott travels to a radar facility in Norway to see the Aurora Borealis.

Sir Patrick Moore and his guests unravel some of the mysteries in the star systems that surround us and look at the latest discoveries from our local galaxies.

Using archive sound, satellite footage and film taken by the astronauts, Patrick Moore presents the story of mankind's first journey to another world. The task of telling Apollo 11’s story from a British angle is a challenging one, since most of the domestic television presentation was not saved for the archives. However, Apollo 11, A Night to Remember, part of BBC Four’s Moon Night, has knitted together the remaining material into an effective two-hour documentary. Satellite pictures have been married up with amateur audio recordings, and linked with rarely-seen reports, background films, a couple of rediscovered studio clips, and some new explanatory pieces by Sir Patrick Moore, one of the presenters in 1969. The satellite images, which form the bulk of the programme, cover the main events in America, in the spacecraft, and on the moon. The source tapes are the BBC’s original 525-to-625 line live electronic standards conversions, but because they are derived from an international signal feed, they are lacking the domestic commentary and captions. However, it has been possible to reinstate much of the commentary from amateur off-air recordings, and thereby restore parts of the BBC’s television coverage. This technique has been applied in previous moon landing documentaries, but here it is used much more extensively than before, greatly enhancing the experience. The sound quality of the amateur recordings is not brilliant; usually it is perfectly intelligible, but occasionally becomes indistinct against all the interference from the space communications. A highlight of the programme comes near the start, when we can savour lengthy sections of what must be one of British television’s most compelling commentaries, as Michael Chartlon dramatically sets the scene at Cape Kennedy’s launch site, then guides us through the last 6 minutes of countdown. There are several technical glitches resulting from a poorish satellite link but these do not de...

July 4th 2005 a small copper impactor from the NASA Deep Impact spacecraft was released in the path of Comet Tempel 1, causing a collision that released fresh ice and dust, allowing astronomers for the first time to study pristine material from the formation of our solar system. Sir Patrick Moore is joined by leading comet experts who describe the science and importance of this historic achievement. While co-host Chris Lintott interviews British astronomer Richard Ellis at Palomar Mountain, California who is in charge of the observatory where professional astronomers using the historic Hale 200-inch telescope, and a team of amateur astronomers including Scott Roberts, Tony Cook, Russ and Stephanie Tanton, Dan Dickerson, John Downs, Mike West, and others who visually and photographically witnessed the actual point of impact.

The Birth of the Universe is an episode from the TV series documentary The Sky at Night.

Sir Patrick Moore celebrates the 700th episode of The Sky at Night at his home in Sussex, with the help of special guests Professor Brian Cox, impressionist and amateur astronomer Jon Culshaw and Lord Martin Rees, the Astronomer Royal. A stellar panel of astronomers gathers to answer vexing questions from the viewers, while Sir Patrick has a close encounter with his younger self.

Patrick Moore presents a retrospective of five decades of The Sky ay Night, recalling the history of space exploration from the first Russian Sputnik, the major astronomical discoveries over half a century, and the people he has met, from Orville Wright to Neil Armstrong.

Using archive sound, satellite footage and film taken by the astronauts, Patrick Moore presents the story of mankind's first journey to another world. The task of telling Apollo 11’s story from a British angle is a challenging one, since most of the domestic television presentation was not saved for the archives. However, Apollo 11, A Night to Remember, part of BBC Four’s Moon Night, has knitted together the remaining material into an effective two-hour documentary. Satellite pictures have been married up with amateur audio recordings, and linked with rarely-seen reports, background films, a couple of rediscovered studio clips, and some new explanatory pieces by Sir Patrick Moore, one of the presenters in 1969. The satellite images, which form the bulk of the programme, cover the main events in America, in the spacecraft, and on the moon. The source tapes are the BBC’s original 525-to-625 line live electronic standards conversions, but because they are derived from an international signal feed, they are lacking the domestic commentary and captions. However, it has been possible to reinstate much of the commentary from amateur off-air recordings, and thereby restore parts of the BBC’s television coverage. This technique has been applied in previous moon landing documentaries, but here it is used much more extensively than before, greatly enhancing the experience. The sound quality of the amateur recordings is not brilliant; usually it is perfectly intelligible, but occasionally becomes indistinct against all the interference from the space communications. A highlight of the programme comes near the start, when we can savour lengthy sections of what must be one of British television’s most compelling commentaries, as Michael Chartlon dramatically sets the scene at Cape Kennedy’s launch site, then guides us through the last 6 minutes of countdown. There are several technical glitches resulting from a poorish satellite link but these do not detrac...

The planets have fascinated us for millennia, but over the past 60 years our understanding of them has been transformed. Using The Sky at Night archives, Maggie Aderin-Pocock takes us on a spectacular voyage of discovery through our exploration of the planets. From incredible technological achievements, to astonishing phenomena such as epic storms on Jupiter and the stunningly complex rings of Saturn, this is the definitive guide to the planets. And the journey doesn't end at the edges of our solar system. We're now discovering that the Milky Way is full of weird and wonderful exoplanets outside our own solar system. Yet the more we learn, the more we discover how special our own planet really is.

Galaxies are the building blocks of the universe. Our solar system sits inside a huge galaxy that we call the Milky Way - home to as many as 300 billion stars. But the Milky Way is itself just one of hundreds of billions of galaxies in the observable universe. Over the last 60 years of broadcasting, the Sky at Night has covered every major story of discovery about the galaxies, and in this film presenter Chris Lintott uses this archive to reveal the deepest secrets of galaxies, from their earliest beginnings to their very ends. From the first galaxy ever discovered through to today's cutting edge attempts to map our own Milky Way, this is a story of incredible ingenuity, extraordinary technology and spectacular discoveries. We'll discover how galaxies work - from the secrets of their spiral arms to the dramatic events that drive their evolution - uncovering a weird and wonderful menagerie of objects along the way. Ultimately, the discovery of the galaxies is also the story of how we found our place in the cosmos, and discovered answers to some of the biggest questions in the Universe.

Chris Lintott opens up The Sky at Night's 60-year archive to reveal how stars work, their life cycles and how their own demise holds the key to our very existence.
