Stellar Evolution Feature Summary

Type:
From Physics Research
Title:
Stellar Evolution
Description:
When the Sun reaches the end of its life, its outer layers will drift into space, an intricate cloud illuminated by its hot, dense core, as in this false-color image of a planetary nebula and white dwarf. For more details, see this page on the death of solar-mass stars.

How a star lives and dies depends upon its mass. For an overview of the lifetime of different types of stars, see The Life and Death of Stars. For very thorough explanations, see the Stellar Evolution pages from the Chandra website.
