The Sky at Night is a monthly documentary television programme on astronomy produced by the BBC.

The show had the same permanent presenter, Patrick Moore, from its first broadcast on 24 April 1957 until 7 January 2013. The latter date was a posthumous broadcast, which followed Moore’s death on 9 December 2012. This made it the longest-running programme with the same presenter in television history. Many early episodes are missing, either because the tapes were wiped, thrown out, or because the episode was broadcast live and never recorded in the first place. Beginning with the 3 February 2013 edition, the show was co-presented by Lucie Green and Chris Lintott. Since December 2013 Maggie Aderin-Pocock has been a presenter. The programme’s opening and closing theme music is “At the Castle Gate”, from the incidental music to Pelléas et Mélisande, written in 1905 by Jean Sibelius, performed by the Royal Philharmonic Orchestra and conducted by Sir Thomas Beecham.

This episode:
Total solar eclipses, like the one seen last month in North America, allow us to see details of the Sun that can’t be seen at any other time. So, this month, The Sky at Night team looks at how scientists are creating eclipses on demand and discovering the secrets that can be revealed hidden in that starlight, including habitable planets like our own. Maggie Aderin-Pocock travels to Belgium, where the European Space Agency’s Proba-3 mission is going through its final testing stages. This groundbreaking mission aims to fly two satellites together in formation, with one satellite acting like the moon during an eclipse, blocking out the central light of the Sun. This allows the other satellite to image the corona, the Sun’s outer atmosphere as seen during an eclipse. Maggie meets Dr Damien Galano from ESA, who tells her all about the challenges of the mission and what it hopes to achieve. Maggie then goes on to meet satellite operations test engineer Marie Beeckman, who takes her up close to the satellites to find out how the testing is going. Meanwhile, Pete Lawrence is out and about in Bristol, meeting a team of scientists and amateur astronomers. He discovers how input from the amateurs was crucial to the discovery of two exoplanets colliding, which had caused the dimming of a star. Finally, Chris Lintott is in Glasgow meeting Professor Beth Biller from Edinburgh University to discover why it is only by creating eclipses of distant stars that we could potentially find exoplanets more like our own. And as ever, our resident astronomer, Pete Lawrence, guides us through what can be seen this coming month, with a particular focus on the rewards of viewing in daylight – but as always, he reminds us of the need to take care when doing this.
