New images taken by the Rosetta space probe have revealed some exciting new things about comets.
The Rosetta space probe was launched back in 2004. After 10 years of travelling through space, Rosetta released its lander Philae last year in November, to make a slightly bumpy touchdown on the surface of comet 67P, moving at thousands of miles an hour. It was the first man-made object ever to land on a comet. Oribiting the comet, Rosetta has continued to send back pictures and information about the high-speed rock - and these are the most detailed yet.
Scientists have split the comet's surface into 19 different areas, and named them after Egyptian gods, such as Seth and Anubis. The comet is quite an unusual shape and has been compared to a rubber duck. It has sections called lobes which are lumpy bits that stick out of the main body of the comet.
The surface of the comet is very rocky and has a lot of craters. It's made up of gas, water and ice, which covers the main body of the comet which is very, very black. A scientist from the University of Maryland in America, who's studying the comet, said: "Comets are effectively twice as black as coal, with a thick dust layer shrouding the surface".
Much of the comet's southern side remains in shadow, and we won't be able to get a clearer view of it, until it passes nearer to the Sun in mid-August this year. You can see faint jets of gas and dust coming off the comet in this photo, because comets have very little gravity. As the comet heats up it will likely change shape or get smaller, as more material floats away from its surface.
Rosetta has two different cameras ten times more powerful than those used for Google Earth. This allows it to capture very detailed pictures of the surface of the comet. As one of the scientists says, "You couldn't see a coffee cup [if one were on the surface], but you could see a large lunchbox." Over the coming months, the mission team hope the comet could tell us more about the origins of life in the universe.
