So Nasa scientists have spotted some mysterious marks on the surface of Mars which they believe are almost certainly caused by flowing water, and now everyone is pretty much flipping out over the fact that there may actually be life on the Red Planet.
Google have created an adorable Google Doodle to celebrate. Boy, do they know how to party.
The moving image shows a plump little Mars spin round, sip from a glass of water and beam with delight. Tweeters are gushing over the little guy.
Look at the face!
