Researchers examined rocks collected by astronauts during NASA's Apollo lunar landing missions, as well as a meteorite that originated on the moon to make the find. They looked for traces of zinc, and found the ratios of heavy to light isotopes are greater than on Earth, which suggests the moon went through an intense evaporation event early in its formation.
The study is more evidence for the theory that the moon formed from a colossal impact, researchers said.
