Supergiants develop when massive main-sequence stars run out of hydrogen in their cores. They then start to expand, just like lower-mass stars, but unlike lower-mass stars, they begin to fuse helium in the core almost immediately.
Supergiants are found throughout the galaxy.
Yes, blue supergiants are significantly hotter than red supergiants. Blue supergiants typically have surface temperatures ranging from about 10,000 to 50,000 Kelvin, while red supergiants usually have temperatures between 3,000 and 4,000 Kelvin. This difference in temperature is due to the varying stages of stellar evolution and the mass of the stars; blue supergiants are more massive and have burned through their hydrogen fuel more rapidly than their red counterparts.
Red supergiants
Giants or supergiants
Both are red supergiants.
they go boom, and make a supernova
Supergiants are bigger and more luminous than the red giants. Supergiants are stars that have a mass that is eight times more than the sun.
The stars that are like supergiants are called "red giants" or "red supergiants".
The five largest known red supergiants in the Galaxy are VY Canis Majoris, VV Cephei A, V354 Cephei, RW Cephei and KW Sagittarii.
Red giants, red supergiants.
Red supergiants have relatively short lifespans compared to other stars, typically a few million years. They spend only a few hundred thousand years in the red supergiant phase before eventually evolving into supernovae or collapsing into black holes.
Yes they are. They're huge!!
