What happens if an astronaut dies in space ?

With the advancement of technology humans are able to travel in space. But no matter how much fascinating this space travel seems, it is full of risks and returning back is not easy. We all knew that the outer space is a huge vacuum that is why i am very curious to know what if an astronaut die in space and what is going to happen with the corpse.
