Hi all, in my intro I said I was a cosmochemist. What does this mean? For practical purposes, it means I use meteorites and other extraterrestrial samples to understand the origin and evolution of the chemical elements in space. So I think I’ll start with a primer on meteorites Image
Meteorites are rocks that fall from outer space. Really large ones kill dinosaurs, somewhat large ones make big holes in the ground, but most are small (from sub-millimeter to meter size) and provide extremely valuable scientific information ImageImage
The vast majority of meteorites come from asteroids (a tiny fraction are known to come from the Moon and Mars), small rock bodies orbiting the Sun between the orbits of Mars and Jupiter . How do we know this? ImageImage
