O-type stars are among the hottest and most massive stars in the universe, with surface temperatures exceeding 30,000 Kelvin. They are typically blue in color and can be up to 100 times more massive than our Sun, known as Sol. Due to their immense energy output, they have short lifespans, often lasting only a few million years before ending in spectacular supernova explosions. These stars are crucial for the evolution of galaxies, as they produce heavy elements through nuclear fusion. Their intense radiation and stellar winds can influence the formation of nearby stars and the surrounding interstellar medium, contributing to the dynamic processes within nebulae and star clusters.
