Star Life Cycles

What is the first stage of the life cycle of a star for all stars?

• nebula

• protostar

• main-sequence

• red giant

In this stage, a star spends most of its life. Hydrogen is fused into helium at a temperature of millions of degrees.

• nebula

• protostar

• main-sequence

• supergiant
