Front

What are Main Sequence stars?

Back

Stars that are in the stable phase of their lifecycle, fusing hydrogen into helium in their cores.

Front

What are Supergiants?

Back

Massive stars that have expanded and are among the most luminous stars in the universe.

Front

What are White Dwarfs?

Back

Small, dense remnants of stars that have exhausted their nuclear fuel and shed their outer layers.
