Stars are made mostly from hydrogen. The more hydrogen available when a star is formed, the more massive it will be.
The massive stars turn into gas
Some massive stars will become neutron stars. When massive stars die they will either become neutron stars or black holes depending on how much mass is left behind.
What I have learned about massive stars is...
Massive stars are most likely to explode faster than smaller stars.
Massive Stars Use Their Hydrogen Much Faster Than Stars Like The Sun Do.
Hydrogen, helium, and carbon fuel are found in more massive stars. The diameter of more massive stars is bigger. Helium is found in greater abundance in more massive stars. The weight of more massive stars is greater.
Stars can emit various forms of radiation, including ultraviolet, X-rays, and gamma rays. Sun-like stars emit primarily visible light and some ultraviolet radiation. More massive stars can also emit X-rays and gamma rays.
Massive stars that are at least eight times more massive than the Sun end their life as a supernova. During the explosion, these stars release a tremendous amount of energy and can briefly outshine an entire galaxy.
Simply put, massive stars come from massive clouds called neblulae.
Generally, yes. For stars on the main sequence, meaning that they fuse hydrogen at their cores, mass, size, color, brightness, and temperature are all closely related. More massive stars are larger, brighter and hotter than less massive ones. The least massive stars are red. As you go to more massive stars color changes to orange, then yellow, then white, and finally to blue for the most massive stars.
No, there are more massive galaxies with stars in them.
The collapse of massive stars - the same as neutron stars.
