Episode 453 - The early days of our solar system

Studying the earliest days of our solar system by looking at meteorites. We don't have to travel to asteroids or dwarf planets in order to study their geology. By studying meteorites we can piece together the mystery behind the formation of our solar system. Asteroids seem to be 'missing' mantle like rock, so how can we find it by studying meteorites? Some meteorites can capture like a time capsule pieces from our early solar system. Some of this leftover bits from the early days of our solar system contain raw pieces from other stars. Sometimes in meteorites you can find matter that has traveled all the way from other stars. References: Nan Liu, Barosch Jens, Larry R. Nittler, Conel M. O'D.
