How do stars form in a nebula?
SpaceStars
Quick Answer
Gravity makes denser parts of a cold gas cloud collapse into protostars. As the core heats up, nuclear fusion eventually begins.
The Full Story
Stars form inside giant molecular clouds, where dust and cold gas can clump under gravity. A region collapses into a protostar, surrounded by a disk that may later form planets. As the core contracts, temperature and pressure rise until hydrogen fusion can start, marking the birth of a main-sequence star. The process typically takes millions of years, not a single sudden event.
Key Facts
1.Star formation happens in giant molecular clouds
2.The collapse phase lasts millions of years
3.Fusion begins once the core becomes hot and dense enough
