Now the birth of a star. The stellar nebula, the mother of all stars. Stars form when the stellar nebula compresses into a ring, and eventually get so packed tight together that they generate thermal energy, until a star is born. After the star is born the run their life cycle of millions/billions of years out until they run out of hydrogen fuel, and have to start fusing helium together to form carbon. When the sun has a helium core it grows hotter, and swells up to “red giants”, some of them so huge they are given the name “super red giants”. After the core is …show more content…
For one smaller stars have way longer life spans than bigger stars (Blue Giants). An average star can outlive a Blue Giant by BILLIONS of years! Also when larger stars become unstable they can explode, and send material flying out into space at 10% the speed of light, are called supernovas. These are super violent, and after could form black holes, or neutron stars that spew out gamma radiation out into space. While when a average star becomes unstable they shed their outer layers and create a planetary nebula. Which has the potential to create whole solar systems. After the star sheds, it leaves it core exposed, and these core become white dwarfs that use stored thermal energy from its fusion days to stay luminicient. But eventually the core begins to cool, and after aa lot of time become black dwarfs (Cooled down star core). But so far there have been no recorded black dwarfs
