Question:
How bright do stars shine?


Replies:
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. samuel p bowen
