Nov 13, 2025 · This article explains the key stages of star formation and stellar evolution, providing a clear overview of how stars are born, live, and eventually die.

1 day ago · Gravity is the force responsible for stellar formation and the mass of material that forms at star largely determines its life and fate.

Overall, every step in star formation is actually important. We understand how galaxies may form, how stars are born and die, and a lot of important parts of how the universe functions.
