Scientists finally pinpoint Jupiters birth using molten rock raindrops

Billions of years ago, Jupiters violent growth transformed the young solar system, smashing icy and rocky bodies together at incredible speeds. These cataclysmic collisions created tiny molten droplets called chondrules-microscopic time capsules later preserved in meteorites. New research shows that water vapor explosions from planetesimal impacts explain their origin, while also pinpointing Jupiters birth at about 1.8 million years after the solar system began. This breakthrough not only rewrit...
