  A star is a huge glowing ball of hot gas (mostly hydrogen and helium) in space. Stars are born, live for millions or billions of years, and then die. This process is called the star life cycle. Star Life Cycle 🌟 1. Nebula (Star Birth Cloud) A star begins inside a giant cloud of gas and dust called a nebula. Gravity pulls the gas together until it becomes hotter and denser. 2. Protostar The collapsing gas forms a protostar — a baby star. The center becomes very hot, and nuclear fusion starts. 3. Main Sequence Star This is the longest stage of a star’s life. Sun is currently in this stage. Hydrogen atoms fuse into helium and release energy: � This energy gives stars light and heat. Different Endings of Stars Small or Medium Stars Stars like the Sun become: 4. Red Giant The star expands and cools. 5. Planetary Nebula Outer layers drift away into space. 6. White Dwarf The small hot core remains. Eventually it cools into a black dwarf over a very long time. Massive Stars Very large s...
