Notes: Life Cycle of a Star
Stars are gigantic spheres of gases held together by gravity. Stars generate huge amounts
of energy due to the hydrogen atoms fusing into helium in their core. The energy is in the
form of electromagnetic radiation which includes light, heat and other forms of energy.
Stages of a Stars Life Cycle
Nebulas are giant clouds of gas and dust in space where new stars are formed.
A supernova is the death of a star by explosion.
A black hole is the final stage in the evolution of a supernova. The core of the star
collapses and causes it’s gravity to become so strong that not even light can escape it!
