Astronomers discover first step toward planet formation
Solving the mystery of how planets like Earth were formed is an important question for understanding the origin of life. Planets are thought to form when interstellar dust and gas collect in a protoplanetary disk surrounding a protostar, but it has b.....»»
New path for early human migrations through a once-lush Arabia contradicts a single "out of Africa" origin
