I post astronomy content on X, Threads, Instagram & BlueskyFuel my stargazing! If you enjoy my daily dose of cosmic wonders, consider buying me a coffee (or a telescope lens!). Your support helps
Developer’s Note Astronomy Bot just got a new update! You’ll notice better space facts and a new feature: short space sci-fi. The space agencies feature has been removed, and Earth images are no longer available on Instagram.

The final evolutionary stage of a star is dictated by its initial mass. Stars less massive than our Sun will cool into white dwarfs, while stars significantly more massive can end their lives as neutron stars or black holes following a supernova.
