Now, NASA has determined that the red planet once had a primitive ocean that may have been larger than Earth's Arctic Ocean, though it has since lost most of its water to space.

Four Times The Fun

Some planets orbit multiple suns. Scientists thought the planets in the 30 Ari star system circle around three stars, but recently a fourth, smaller star was found. This is the second four-star system discovered so far, but NASA thinks they could be more common than astronomers once imagined.
