Subsequently, one may also ask, what happens at the end of a stars life?
Most stars take millions of years to die. When a star like the Sun has burned all of its hydrogen fuel, it expands to become a red giant. Stars heavier than eight times the mass of the Sun end their lives very suddenly. When they run out of fuel, they swell into red supergiants.
One may also ask, what do stars look like when they die? Nuclear reactions outside the core cause the dying star to expand outward in the "red giant" phase before it begins its inevitable collapse. If the star is about the same mass as the Sun, it will turn into a white dwarf star. The star implodes to form an infinite gravitational warp in space -- a black hole.
Then, what are the three end stages of stars?
The expanding star is now called a Red Giant. Stage 8 - The helium core runs out, and the outer layers drift of away from the core as a gaseous shell, this gas that surrounds the core is called a Planetary Nebula. Stage 9 - The remaining core (thats 80% of the original star) is now in its final stages.
What is a star's life cycle?
A star's life cycle is determined by its mass. The larger its mass, the shorter its life cycle. A star's mass is determined by the amount of matter that is available in its nebula, the giant cloud of gas and dust from which it was born. The outer shell of the star, which is still mostly hydrogen, starts to expand.
