Answer

Stellar Nebula → Protostar → Main Sequence → Red Giant → Planetary Nebula → White Dwarf Explanation 1. Stellar Nebula A medium-sized star begins its life in a stellar nebula, a cloud of gas and dust. 2. Protostar Formation Gravity pulls the nebula together to form a protostar, where nuclear fusion starts. 3. Main Sequence The star enters the main sequence phase, fusing hydrogen into helium in its core. This is the longest stage. 4. Red Giant Once hydrogen is depleted, the core contracts and the outer layers expand, forming a red giant. 5. Planetary Nebula The outer layers are ejected, leaving behind a hot core. 6. White Dwarf The remaining core cools and becomes a white dwarf, eventually fading over time.
