8 to 20 Times the Sun’s Mass

High-mass stars are very luminous and short lived. They forge heavy elements in their cores, explode as supernovas, and expel these elements into space. Apart from hydrogen and helium, most of the elements in the universe, including those comprising Earth and everything on it, came from these stars.
