Episode 464 - Rogue Planets and glass in meteorites

January 3, 2022

Rogue planets hurtling across space without a place to call home. How do we detect intergalactic nomads like Rogue planets? Just how many rogue planets are out there? Are there rogue planets lurking in our own solar system? Glass inside meteorites can help us understand early earth. How does meteorite rock differ from rock here on earth?
