Stars as the building blocks of the unvierse

Stars are the workhorses of the universe and account for most of its mass. They come in many shapes and sizes, some as small as just a few miles across and others that are as large as much of our solar system. Some are hundreds of times hotter than the Sun and others are just a few thousand degrees. When stars start running out of fuel they do some crazy things like explode into supernovae or implode into tightly packed white dwarfs or black holes.
