Chronological sequence of stellar evolution

WebStellar evolution begins with the gravitational collapse of a giant molecular cloud. Typical giant molecular clouds are roughly 100 light-years (9.5×10 14 km) across and contain up to 6,000,000 solar masses (1.2×10 37 kg). As it collapses, a giant molecular cloud breaks into smaller and smaller pieces. WebMay 11, 2024 · Stellar evolution. The mass of a star determines the ultimate fate of a star.
