SUMMARY:The Sky at Night - Space Rock Return (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:\nThe Sky at Night is back for a brand new series\, and this month it is delving into Nasa’s OSIRIS-REx mission\, which last year brought back a sample from the near-Earth asteroid Bennu. The team are finding out what it takes to analyse the tiny pieces of space rock\, what they can tell us about how Earth became the planet it is today and may even tell us about the origins of life! \nWe kick off the episode with a catch-up on some of the astronomical news highlights since we have been off air and a quick history of asteroids. Chris Lintott then meets Professor Sara Russell and Dr Ashley King from the Natural History Museum in London\, who were both involved with the Osiris Rex mission to Bennu. Chris discovers the challenges it encountered\, from unexpected landing surfaces to problems opening the sample jar once it had returned. Chris then goes on to hold a piece of the asteroid itself and finds out about Sara and Ashley’s work on the space rock and the complex picture it is giving of Bennu’s history. By understanding the journey the asteroid has been on\, they can learn more about the conditions in which the Earth formed and how our planet became the water rich place it is today. \nMeanwhile\, Maggie Aderin-Pocock heads to Diamond Light Source to meet Dr Sharif Ahmed. He explains how the very large machine housed there produces light 10 billion times brighter than the sun\, from which powerful X-rays are created\, allowing scientists to analyse the very smallest of samples. \nFinally\, George Dransfield heads to Royal Holloway University to meet Dr Queenie Chan\, who is looking for tiny bubbles of liquid in the space rock samples\, in which she may discover the secrets of how the building blocks of life could have formed. \nAnd as ever\, our resident astronomer\, Pete Lawrence\, is back to tell us what can be seen in this month’s night sky. \nLinks:\nThe Sky at Night \nTag: skyatnight
