The infant moon may have had a thick metal atmosphere, where supersonic winds raised waves in its magma ocean.
That’s the conclusion of a new simulation that calculates how heat from the young sun, the Earth and the moon’s own hot surface could have vaporized lunar metals to give the moon an atmosphere as thick as Mars’. The model, reported online June 22 at arXiv.org, offers a way to test theories of how the moon formed and suggests how researchers could study exoplanets without leaving Earth’s own neighborhood.
