On 4 July NASA hopes to send an impactor into the comet 9P/Tempel-1. Patrick Moore talks to the world's leading comet experts about the fallout from this destructive act. Chris Lintott reports from Palomar Observatory in California, where astronomers will be eagerly watching the comet to see what happens when Deep Impact hits its mark.

Chris shows us how to see Saturn with a small telescope, while Patrick finds out the latest from the Cassini mission currently orbiting the planet.

The Sky at Night 50th birthday party. Patrick reflects on how astronomy has changed over the last half century, with amusing clips from the archives.

Dr Chris Lintott finds out how British technology is leading the way in satellite science, while Sir Patrick Moore investigates the threat from space debris that astronauts face in space.

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.

Sir Patrick Moore charts the development of the telescope over four centuries and fasts forward to meet the astronaut who repaired the Hubble Space Telescope. Dr Chris Lintott visits some modern day astronomical leviathans.

Patrick Moore tells the story of the race to discover Neptune 150 years ago.

Voyager 2, launched in 1977, has already passed by the giant planets Jupiter, Saturn and Uranus, all of which have provided plenty of surprises. Voyager has now passed Neptune, sending back remarkable new information about the outermost planet. In this programme, Patrick Moore is joined by Dr Garry Hunt and other experts from the American team to summarise what has been discovered about this lonely, remote world.

On 14th December 1972, Captain Eugene Cernan left the Moon to return to Earth. He had no idea that, 25 years later, he would still be the last man to have left his footprints on the lunar surface. Dr Chris Lintott travels to the Johnson Space Centre to talk to the Commander of Apollo 17 about his memories of being on the Moon. Sir Patrick Moore looks at lunar samples brought back by the astronauts and talks to NASA scientists about what they discovered.

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.

In this historic interview Patrick Moore talks to Professor Stephen Hawking about his cosmological theories and finds out how our Universe started.

Patrick Moore shows what to look for in the night sky during the coming month.

Patrick Moore shows what to look for in the sky during the coming month.

This month the three outermost planets - Uranus, Neptune and Pluto - are all on view, even though they are faint. Each has its own special points of interest; and Patrick Moore talks about these remote members of the Sun's family.

Martin Rees is perhaps Britain’s most renowned cosmologist. Now, about to celebrate his eightieth birthday, Lord Rees talks to Chris Lintott about his career in science.

The Sky at Night in the Multiverse of Mystery is a magical journey into the far-flung ideas at the very edge of scientific knowledge, exploring the concepts that today seem like science fiction but may one day become science fact. Delving into the archive at the Royal Society, we look at the dreamers who first considered the possibility of travelling to the moon and black holes long before they could be proven to exist. From there, the team explore some ideas and theories that today could be dismissed as fanciful thinking.

Celebrating 50 years of The Sky at Night, Patrick 'travelled' back to the show's first ever recording in 1957. The episode then jumped forward to 2057 where the 'virtual' Patrick talked to Dr Chris Lintott and Dr Brian May on Mars. Jon Culshaw's turn as a younger Patrick was uncanny as he recreated Patrick's first words on The Sky at Night.

Patrick Moore tells you what to look for in the night sky during the coming month. The first of a regular monthly series.

This month, The Sky at Night has a spooky twist. Across the universe, there are hidden objects that we can’t see, but astronomers and scientists still believe they’re out there. To find out how we know that these mysterious objects exist, the team are going ghost-hunting. Cosmic ghost-hunting.

A new probe is being launched toward Titan, Saturn's largest satellite.

The Very Large Telescope has been responsible for some of the greatest astronomical breakthroughs. For September 2023, the team travels to the heart of the Atacama to explore one of the most advanced observatories in the world, a site at the forefront of astronomy.

Patrick Moore shows what to look for in the night sky during the coming month and discusses telescopes with Henry Wildey.

New scientific methods to discover exoplanets, and how the winter dakness in Antarctica helps here.

The British weather is often the enemy of stargazers up and down the country. A forecast of a couple of hours of cloud cover will disappoint even the most determined amateur astronomers. In this programme, the Sky at Night becomes the 'Sky at Day', providing an alternative range of spectacles to observe and activities to partake in, ideal when the nights are short and the stars are hiding behind the clouds.

For centuries, humans have been drawing what they see in the night sky through telescopes. But there is something about a photograph that can make you feel you are right there, up close to the moon, planet, star or galaxy you are looking at. Having the light from those distance objects, fixed in an image, has meant scientists can analyse and understand the beautiful universe around us. So, this month, the Sky at Night is looking at the wonderful world of astrophotography.
