The Complete Guide Sky at Night

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 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!

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 Sky at Night team investigates the controversial world of alien communication. The search for life on other planets is one of the most fascinating subjects in science. But what is less reported is the work being done around the world to determine what happens next. If we discover aliens, how would we contact them, what should we say and should we communicate with them at all?

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.

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.

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 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.
