Chronological sequence of stellar evolution
Did you know?
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. WebStars are predominantly composed of hydrogen (71%) and helium (27%) gases, with traces of heavier elements such as oxygen, carbon, neon …
