red super giant

Answer 1

A red supergiant is a massive star in the late stage of its evolution. It is characterized by its large size and cool surface temperature, which gives it a reddish appearance. These stars are among the largest in the universe, with radii that can be hundreds of times greater than the Sun. Red supergiants are known to undergo dramatic and explosive events, such as supernovae, at the end of their lives. Betelgeuse, located in the constellation Orion, is a famous example of a red supergiant.
