Exobiology – 23rd September 2004

Mike Leggett, a member of the Astrobiology Society of Britain came to High Elms to give us a talk with the title Exobiology: Life Beyond the Earth?. From the start this engaged the interest of members, and there were several questions from the floor. Mike answered them while also keeping his talk on track. He took us through the history of the idea of life beyond Earth from the ideas of the ancient Greeks to modern times. He then gave us a brief explanation of the processes that are currently believed to be involved in the appearance of life and some estimates of the probability of it appearing elsewhere, and rounded the talk off with some speculation about whether there might be life on other moons and planets in our solar system. The subject is clearly one from which several more talks could be drawn, and discussions continued afterwards in the Change of Horses
