Star Life Cycle

The Cycle

  • Nebula
  • Star
  • Red Giant
  • Red Dwarf
  • White Dwarf
  • Supernova
  • Neutron Stars
  • Black Holes


The birthplace of a star, made of hydrogen floating in space.


They can be brighter than one-million suns!

Protostar *

The stars materials, hydrogen and helium, coming together to make the star, in this situation for it to maintain life it must keep equilibrium. More specifically, pushing the atoms inward and heat and light outwards.

Main Sequence

A main sequence star is a star that are using fusion to make hydrogen atoms into helium atoms.

  • 90% of stars are main sequence stars, including the Sun

Red Giant

A dying star in its last stages of life.

DEATH OF A STAR!!!!!!!!!!

  1. Will die once it runs out of hydrogen fuel
  2. Starts to fuse helium into carbon
  3. The mass is enough to start making new elements such as; silicon, oxygen, magnesium, sulfur and iron
  4. The outer layers fall inwards, crushing it
  5. The core will heat up and explode
  6. Next it turns into either a black hole or an neutron star
