[|Enchanted Learning]   These notes will also help you. We will discuss them in class : 1. A star starts its life as a giant cloud of gas and dust called a NEBULA. This is when a star is a protostar - or a young star. 2. Once a star reaches a temperature of several million degrees - nuclear reactions occur. The protostar becomes a main sequence star. The main sequence star is a star that is fusing hydrogen into helium. 3. Most of a stars life is spent being a main sequence star. 4. Depending on the size (mass) a star will then either become a giant or super giant. 5. A supernova is a star that explodes! 6. A blackhole is when an object has so much gravity that light can not escape.
