The Sky at Night

The team explore Nasa's Artemis II mission, the first crewed journey towards the moon since 1972. They also look into robotic landers and new scientific clues from lunar samples.

The team explore the remarkable story of Jodrell Bank Observatory and its towering Lovell Telescope, which scientists have used to listen to the cosmos for almost 70 years.

The team uncover a danger that humanity is only just waking up to – space weather. They meet the dedicated people working to keep us safe from the very worst that the sun can throw at us.

Could alien life exist closer than we think - perhaps right next door? A paper published in 2025 suggested that strange markings discovered on Mars could provide some of the strongest evidence yet that life once existed on the Red Planet. The Sky at Night team travels across Great Britain to investigate this and other evidence that suggests the search for life beyond Earth may lie within our own solar system. Off the east coast of Scotland, Chris Lintott meets Dr Claire Cousins, who explains the fundamental conditions needed for life. She then turns to the ground beneath their feet, where the red rocks along the North Berwick coastline are marked with patterns similar to those seen on Mars. To find out more about how these markings could have formed here - and possibly on Mars - Chris heads to Edinburgh, where Dr Sean McMahon is investigating whether similar patterns can be recreated in the lab. Meanwhile, in Cardiff, George Dransfield speaks with Professor Jane Greaves, whose paper on the detection of phosphine in the clouds of Venus six years ago caused a stir. Did the phosphine truly exist, and could it point to life? Ongoing research is continuing to build the case for unusual chemistry - and possibly life - on our closest planetary neighbour. Further out in the solar system, the icy moons of Jupiter and Saturn offer another compelling possibility. Maggie Aderin-Pocock is in Milton Keynes to meet Dr Mark Fox-Powell, whose team are recreating these freezing conditions in the lab to understand how chemistry behaves there. Their work is helping identify what future missions to these icy worlds should look for as potential signs of life - and has even led to the discovery of a new mineral that can only form in such extreme environments. Across Mars, Venus and the icy moons, one theme emerges: life may not require Earth-like conditions in the way we once assumed. Instead, it could thrive in unexpected environments. Finally, Pete Lawrence rounds off the programme with a tour of the summer night sky, and we are reminded of how vast our galaxy is and how small our place within it really is. So, are we alone? The search continues - right here on our cosmic doorstep.

Professor Brian Cox joins the team to explore the mind-bending mysteries of black holes discovered by the James Webb Space Telescope's most exciting new observations.

Chris Lintott and the team explore the extraordinary engineering, both on Earth and millions of kilometres above it in space, that is transforming modern astronomy and revealing parts of the cosmos once thought forever beyond our reach. George Dransfield travels to Marseille to investigate KM3NeT, one of the most ambitious scientific instruments ever constructed. Covering more than a cubic kilometre of the Mediterranean Sea, this vast underwater observatory is searching for neutrinos, elusive 'ghost particles' that pass through planets, stars and even our own bodies almost entirely unnoticed. By detecting these cosmic messengers, astronomers hope to uncover the origins of some of the most violent and energetic events in the universe, from exploding stars to the environments around supermassive black holes. The programme also explores gravitational-wave astronomy and the remarkable international network of detectors capable of measuring distortions in space-time smaller than an atom. These instruments have opened an entirely new way of observing the cosmos, allowing scientists to detect collisions between black holes and neutron stars across the universe. In Cambridge, Chris visits a team attempting to tackle one of cosmology's biggest mysteries using a tabletop experiment. By cooling atoms to almost absolute zero and manipulating them with ultra-precise lasers, researchers are building a laboratory system that could one day probe some of the quantum physics thought to have shaped the universe in its earliest moments. Finally, Maggie Aderin explores Nasa's Nancy Grace Roman Space Telescope, a new observatory designed to search for distant worlds beyond our solar system. Its revolutionary coronagraph will suppress the overwhelming glare of distant stars, potentially allowing astronomers to directly image planets orbiting them and paving the way for future missions that could search Earth-like worlds for signs of life. From particle detectors deep beneath the Mediterranean to ultra-cold quantum experiments and next-generation space telescopes, this programme reveals how human ingenuity is creating entirely new ways to explore the cosmos and uncover its deepest secrets.

Maggie Aderin explores how dyslexia has affected her life and career by meeting other dyslexic astronomers and discovering their research – from icy moons to clumpy galaxies.
