Stars are born inside giant clouds of gas and dust called nebulas. The gas clumps together and gets hotter and hotter until a new star lights up! The star shines for millions or billions of years by burning its fuel. When the fuel runs out, small stars shrink into tiny white dwarfs. Big stars can explode in a giant blast called a supernova!
- Our Sun is a middle-aged star that is about 4.6 billion years old.
- When a big star explodes, the leftovers can form a new nebula where baby stars are born.
- Some old stars collapse and become black holes, which are the most mysterious objects in space!
