A Blue Supergiant is a massive star that is significantly larger and hotter than our Sun. These stars are typically more than 10 times the mass of the Sun and can be thousands of degrees hotter, emitting a blue light. They are often found in the later stages of stellar evolution, burning through their nuclear fuel at a rapid rate. Due to their immense size and energy output, blue supergiants have relatively short lifespans, usually lasting only a few million years. They eventually end their lives in spectacular explosions known as supernovae, leaving behind remnants such as neutron stars or black holes.
