SUMMARY:The Sky at Night - Cosmic Ghosts (TV BBC Four)
DESCRIPTION:The Sky at Night is a monthly documentary television programme on astronomy produced by the BBC. \nThe 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. \nBeginning 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. \nThis episode:\nThis 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. \nProf Chris Lintott and Dr Maggie Aderin-Pocock are at Provan Hall\, one of the oldest buildings in Glasgow and the site of several supposed ghost sightings across its 550-year history. But they aren’t looking for anything supernatural. Instead\, they’re meeting the scientists and astronomers trying to solve some of the universe’s greatest mysteries by finding new ways to sense what surrounds us in the cosmos. \nIn the medieval rooms of Provan Hall\, Chris meets Dr Olivia Jones from the UK Astronomy Centre and discovers how a tool often employed by ghost hunters is actually great for finding objects hidden in the dust of the cosmos. He also meets Prof Tessa Baker from the University of Portsmouth\, who shows him how ripples in space-time are helping scientists to detect new\, unseen cosmic events. And while scanning the house for spooky sounds\, Maggie hears a voice from the past\, which leads her to uncover the wonderful work of Vera Rubin – a trailblazing astronomer who helped to prove the existence of dark matter. \nAcross the country\, and over a kilometre further below the Earth’s surface\, guest presenter Prof Chamkaur Ghag is at the Boulby Underground Laboratory. While there\, he discovers how the incredible research site has changed since Patrick Moore and The Sky at Night team visited 20 years ago and meets some of the Boulby team who are working on the hunt for ghostly dark matter particles. \nMeanwhile\, Pete Lawrence is at the Bedford School Observatory to show us how to find and photograph inky\, ghost-like objects in the sky known as dark nebulae\, and to tell us what to look out for in the night sky over the next month. \nLinks:\nThe Sky at Night
