Life Cycle of Stars
Understand the basics of a star’s life cycle: stars are born in clouds of gas and dust (nebulae), shine for millions or billions of years by fusing hydrogen, and eventually die — massive stars explode as supernovae while smaller stars fade into white dwarfs

Check understanding
- Describe that stars form from clouds of gas and dust called nebulae
- State that stars produce energy by fusing hydrogen into helium in their cores
- Explain that massive stars end in a supernova explosion while smaller stars shrink to become white dwarfs
“Can your child explain that stars are born, live for a very long time, and eventually die — and that really big stars can explode at the end?”
