How bright do stars shine?
The amount of light a star emits depends on how much nuclear fuel is
being consumed and on whether any of the emitted light can escape the surface of
the star. The light a star emits during its lifetime will change. When a star
exhausts its nuclear fuel, it can expand and become a red giant, or it can colla pse and become a
black hole. There is lots known about stars and the life they evolve through.
