See for Yourself ..... Click on the Pictures
These are some pictures of what's left after stars, like the sun run out of fuel. The clouds of gas that you see are actually the outer layers of the original star. At the center of the gas cloud is all that is left of the star that started it all. After some time, we will no longer be able to see the gas cloud and all that will be left is the burnt out remains of the old star, called a white dwarf.
