Blue giants are massive stars that are significantly larger and hotter than our Sun. They typically have a surface temperature exceeding 10,000 Kelvin and can be up to 20 times more massive. These stars are often found in the later stages of their evolution, burning through their hydrogen fuel at an accelerated rate, which leads to their short lifespan of only a few million years. Due to their immense brightness and size, blue giants play a crucial role in the chemical enrichment of the universe. When they reach the end of their life cycle, they may explode as supernovae, dispersing heavy elements into space and contributing to the formation of new stars and planets.
