Star Life Cycle Explained: From Protostar to Black Hole #3730229 (License: Personal Use)

The diagram maps stellar evolution pathways: low- to medium-mass stars follow the main sequence → red giant → planetary nebula → white dwarf path, while high-mass stars progress through red supergiant → supernova → neutron star or black hole. A protostar forms from a stellar nebula, and the main sequence phase is where hydrogen fusion occurs steadily. The divergent endpoints highlight how mass dictates a star’s ultimate destiny.

Used in astronomy education,科普 articles, and introductory astrophysics webpages; targets students, educators, and space enthusiasts seeking a clear, visual summary of stellar evolution. Matches user intent for understanding cosmic lifecycles and stellar classification.
