Massive stars are celestial bodies that have a mass greater than eight times that of our Sun, known as Sol. They burn their nuclear fuel much faster than smaller stars, leading to shorter lifespans, typically ranging from a few million to a few hundred million years. These stars undergo a series of complex processes, including nuclear fusion, which produces heavier elements. Eventually, they end their lives in spectacular explosions called supernovae, leaving behind remnants such as neutron stars or black holes. Their formation and death play a crucial role in enriching the universe with elements necessary for the formation of planets and life.
