The moon was once covered by an ocean of molten rock, data from India's space mission suggests

Probably from when it got popped out of Earth by a massive strike, which is I believe the theory.

Although, I think our theories say that most planets have an ocean of molten rock at some point in their creation, right? Isn't that part of the planet creation process?

Though of course, finding actual evidence to support those theories is always good.

Imagine the view from Earth!
