The life cycle of a star can follow a few different paths depending on the mass it starts out with. Really massive stars may live for only a few million years before going supernova, while low mass stars such as the Sun may take billions of years to use up their fuel and then die relatively quietly.he life cycle of a star can follow a few different paths depending on the mass it starts out with.

Generally stars spend most of their active lives travelling through the stage of stellar life-cycle known as the. Main Sequence. I say 'active' life because the remnants of dead stars can persist more or less indefinitely, slowly fading into obscurity. I say 'generally' because even dead stars sometimes find ways to obtain new life (see stellar accretion for example). Main sequence stars fall into several spectral classes, as shown above. Going from top left to bottom right we have, a small dim red dwarf (spectral class M), an orange dwarf (spectral class K) a yellow dwarf, like the Sun
