APOD 3.4

              This image first appealed to me as I had been watching lord of the rings and it reminded me of the giant eye at the top of the tower in the movie. The image above is of the the helix nebula from the vista telescope. The nebula is what forms after after a star. When a sun like star diminishes a gas like cloud called a nebula can form. The image is taken in infared as the colors of the nebula would be unseen to the naked eye. Its confusing to think that when a star nears the end of its life it basically explodes. Sending debris in every direction. Why would there be anything left? Would not all of the debris be sent, scattered across space. What force holds material back to create a object such as this?
