The famous arcade character was revealed on the Saturn moon of Mimas, by the Cassini spaceship, which was mapping daytime temperature patterns.
Mimas is about 250 miles in diameter, composed mostly of water-ice, and is most famous for having a crater - known as the Herschel Crater - that gives it the look of the Death Star from the Star Wars movies.
Saturn has a staggering 62 moons altogether, with Titan being the largest. It's 50 per cent bigger than our own moon and is the only moon in the solar system known to have a dense atmosphere.
The Cassini project is being run by Nasa, the European Space Agency and the Italian Space Agency – and is operating until 2017.
