Massive stars are celestial bodies that have a mass greater than eight times that of our Sun, known as the Sun. 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 are often much brighter and hotter, emitting intense radiation and creating powerful stellar winds. When massive stars exhaust their nuclear fuel, they undergo dramatic transformations. They can explode in a spectacular event called a supernova, leaving behind remnants such as neutron stars or black holes. These processes contribute to the formation of new stars and the enrichment of the interstellar medium with heavy elements.
