Stars have the power of a atomic bomb that comes from nuclear fusion. 

Stars are mostly made of  

This keeps a star from collapsing under its own gravity. 

Fusion is 

Extremely high temperature stars are what color? 

The brighter the star, the colder it is. 

The Hertzsprung-Russell diagram shows 

Red stars are the coolest.

A star in the life cycle stage where it fuses hydrogen into helium is called 

Our sun has been a main sequence star for approximately 

Red giant stars are cooler and will soon collapse

When there are no more elements left for a MASSIVE star to fuse, the core will collapse under its own gravity creating a violent explosion called 

If there is any material left over after a supernova explosion, this can be made into a 

The path a star takes as it dies depends on 

Which types of electromagnetic radiation does our sun produce?
