Stars are the reason us humans exist. The one we look up to is called the sun. The sun is the name we humans have given to the closest star to us. Stars are like the engines for life, literally. Stars work like an engine. There composition is mainly hydrogen and helium, which are two of the factors or building blocks for life. There are many kinds of stars and stages they go through, and what I find especially fascinating , is the ending life of a star. When a star is near its death it forms into a Red Giant. A Red giant is when the core of the star slows dramatically and you can see the light fading from it and when it does there are two thing that could happen. One of these is a supernova. A supernova is when the star explodes emitting mass amounts of radiation and luminous enough to outshine a entire galaxy. Alternative number two is that it turns into a planetary nebula and then slowly dissipates into a white dwarf which is the barley lighted core of a star.
