starbirth
Nebula becomes sun
Starbirth is the formation of a star from collapsing clouds of gas and dust.
The process takes millions of years as gravity pulls matter together until nuclear fusion ignites.
Astronomers study stellar nurseries—regions where starbirth occurs—to understand how solar systems form: The Orion Nebula is a site of active starbirth.
