Meteorites

Adam Walton discusses meteorites, asking where they come from and what they tell us about the universe?

Joining Adam is Dr Tim Gregory, whose book 'Meteorite: The Stones from Outer Space that Made Our World', takes us on a historical and scientific journey from the Big Bang to the present day.

And we join National Museum of Wales Head of Mineralogy & Petrology, Dr Jana Horak, to talk about the Fireball Alliance Group and meteorite monitoring activities here in Wales.
