Black hole:
the result of a massive star collapsing. Gravity acts so strongly on black holes that nothing can escape it.

Brown Dwarf:
Collection of matter that could not achieve nuclear fusion.

Protostar:
cloud of gas that is beginning the process of nuclear fusion.

Main Sequence:
Longest part of a star's lifespan. Stars with larger mass have shorter main sequences. Stars with smaller mas have longer main sequences.

Neutron stars:
One of the last stages of a mid-sized star. Neutron stars have a core of densely-packed neutrons.

Red giant:
Stage in a star's lifespan in which it burns helium instead of hydrogen.

Supergiant:
Another name for a red giant. Supergiants are larger than red giants.

White Dwarf:
Stage in which a star stops fusion. White dwarfs can have high temperatures, but they produce less light than a star in main sequence.
