Enceladus' ocean is about 6 miles deep and lies beneath a shell of ice 19 to 25 miles thick. Further, it's in direct contact with a rocky seafloor, theoretically making possible all kinds of complex chemical reactions.

Using data from a close fly-by of the moon by NASA Cassini probe, researchers have suggested that there is something dense beneath 18 to 24 miles of ice. Liquid water is the most likely suspect, Sapienza Università scientist Luciano Less explains.

After gazing up at the moon for thousands of years, we're still not exactly sure how it came to be. Here's a brief rundown of the most prominent theories scientists have come up with to explain the moon's origin.

The dusty surface of small asteroids is born by extreme temperature shifts between periods of sunlight and darkness, a cycle of drastic changes that break up space rocks over time, scientists say.
