  • Nubula
    • Protostar
      • Main star sequence
        • Red Giant
          • White Dwarf
            • Black Dwarf
              • Cools down and eventually disappears.
            • Whats left behind after a red giant. It is a dense solid core.
          • Untitled
          • This is smaller than the sun. It is unstable so it loses its outer layer of dust and gas.
        • Red Super Giant
          • Supernova
            • Neutron star
              • This is what is left over after the supernova throws its outer layers into space. It is very dense.
            • Black Hole
              • If a star is big enough it will become a black hole that light cant even escape.
            • It glows like a star but is much bigger so it forms elements as heavy as iron.
          • After a while the hydrogen runs out . The star then swells and folds in on its self.
          • Three times bigger than the sun.
        • This star is stable for a long time. The pressure produced by heat is equal to the gravitational force.
      • Clouds of dust and gas forced into a clump by gravity.
