Season 2021 - Episode 5 - Aired 7/11/2021

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. Such luminaries as Patrick Moore, Arthur C. Clarke, Carl Sagan, James Burke and Alan Whicker discuss the eternal question of whether we are alone. The story of how the BBC has covered advancements in this scientific field is told from the birth of radio astronomy in the 1960s to the discovery of the first planets outside of our own solar system in the 1990s, and right up to probes exploring our neighbouring planets in the present day. There are also some rather more offbeat claims of UFO sightings, alien abductions and accounts of humanoid-like beings that supposedly live on Venus.

#4 - Juno and Jupiter

Season 2021 - Episode 6 - Aired 8/8/2021

August 2021 marks ten years since NASA’s mission to Jupiter, Juno, was launched. The mission – to uncover the mysteries surrounding Jupiter’s formation – was expected to end this year with the $1.1 billion satellite deorbiting into the planet’s gassy atmosphere. But thanks to the ingenuity of its engineering, the robust spacecraft has surpassed expectations and been granted an extension to its life. The Sky at Night looks at the amazing research that has resulted from this mission, expanding our understanding of the gas giant and explaining how Juno will now use its extra time in orbit to gather information for future Jupiter-bound missions – NASA’s Europa Clipper and the European Space Agency’s Juice mission.
