This week marks 150 years since the first issue of Nature was published, on 4 November 1869. In this anniversary edition of Backchat, the panel take a look back at how the journal has evolved in this time, and discuss the role that Nature can play in today's society. The panel also pick a few of their favourite research papers that Nature has published, and think about where science might be headed in the next 150 years.Collection: 150 years of Nature Hosted on Acast.

This year, Nature celebrates its 150th birthday. To mark this anniversary we’re rebroadcasting episodes from our PastCast series, highlighting key moments in the history of science.In the early 1990s, a team of astrophysicists led by Carl Sagan looked at data from the Galileo spacecraft and saw the signatures of life on a planet in our galaxy. Historian of science David Kaiser and astrobiologists Charles Cockell and Frank Drake discuss how we can tell if there is life beyond the Earth – and how optimism, as well as science, is necessary for such a venture.This episode was first broadcast in October 2013.
