- This is where a new star is born: in a cloud of gas called a nebula.
- The gas and dust inside will eventually start to fuse together, forming a protostar, and then a main sequence star.
- The nuclear reactions inside the star produce energy which in turn emits light. Our sun is in the main sequence currently.
- The stars will continue to use this energy until they run out of fuel; however, this will not happen until billions of years later.
- The stars will continue to use this energy until they run out of fuel; however, this will not happen until billions of years later.
- When the stars are running out of fuel, it begins to start to expand and become a red giant
- When the red giant finally runs out of fuel, it will cool down and stop glowing. It's at this time that it's outer layers shed off and become a planetary nebula.
- It's at this point that the outer layers leave behind a very dense and hot white core called a white dwarf. It will eventually become a nuetron star.
