The Life of A Star


A large cloud of dust is called a nebula. When the nebula becomes large enough for its gravity to overcome its gas pressure then it starts to collapse. Once the nebula has collapsed all that’s left is a star. This is how stars are born. Once a star runs out of helium it starts to collapse. The star becomes increasingly hotter and larger. When a star finally dies it creates a super nova. Then the star can go onto become a brown dwarf, a white dwarf, or a black hole. Brown dwarfs are larger than planets but smaller then a real star. A white dwarf will live forever if the universe does not end.
