The asteroid Psyche may have once had vents that spewed molten metal — but only if it is chemically similar to rare, metal-rich meteorites, a new study suggests. The study, which was published online July 31 in the Journal of Geophysical Research: Planets, could explain why the space rock has an unusual metallic cloak. Potato-shaped asteroid Psyche, a member of …

When asteroids hit the Moon, the impacts carve out craters and with enough energy and pressure, melt parts of the rocky surface. Often, the white hot, gooey melt (it’s like lava, except that it doesn’t erupt from underground) sloshes around the new crater and surrounding regions. The molten rock cools and hardens into vast rock features called impact melt flow …
