Imagine an explosion with a magnificent display greater than the atomic bomb. Imagine life from destruction. Imagine something capable of outshining an entire galaxy. Imagine what can form an incredible nebula. If you can imagine all of this, then you can imagine a supernova. When a star ends its life with a bright and strong ending, a supernova occurs. A supernova emits enough energy to run an entire galaxy. A supernova occurs only once every few years. They are an uncommon occurrence and rarely visible sight. By February 24, 1987, only three supernovas were ever recorded. During that year, it was seen from the Southern Hemisphere from another galaxy. It left a large gigantic cloud. The famous crab nebula was left from a supernova that occurred in the year of 1054. The supernovas seem to leave expanding shells of gas. Although a supernova has been described as an explosion and death of a star, in actuality, it is feasible to see it as a stage of development for the rebirth of a new star.
