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 90 times more massive than our Sun, known as Sol. Due to their immense energy output, O-type stars have short lifespans, often lasting only a few million years before ending their lives in spectacular supernova explosions. These stars are crucial for the formation of heavy elements in the universe. Their intense radiation and stellar winds can influence the surrounding interstellar medium, contributing to the birth of new stars and shaping galaxies. O-type stars are often found in clusters, such as the Orion Nebula, where they play a significant role in the dynamics of star formation.
