The Solar System’s First Planets Were Made of Fire, Not Ice

The early stages of the solar system remain shrouded in mystery. Not much remains from that time, but scientists have developed plenty of theories about what was going on back then. One of those theories attempts to answer a simple question - did the early system prefer “fire” or “ice”? A new paper published in Nature Astrophysics from lead author Damanveer Grewal, an assistant professor of Earth and planetary sciences at Yale, and his co-authors, have a definitive answer to that question - the early solar system preferred fire.
