A heaven-sent opportunity to talk about science, organised by the University of Bristol in association with the Royal Society, delivered by Professor Colin Pillinger CBE FRS.
Stones that fall from the sky, meteorites, were first confirmed as scientific objects when a 56lb stone fell on farm land in Yorkshire in 1795. With more than 40,000 samples now confirmed as specimens from asteroids, the Moon and Mars have plenty of stories to tell and each provides an opportunity to interest people in science.
