Scorpius OB2 is a large star-forming region located in the constellation of Scorpius. It is part of a group of massive stars known as an OB association, which are characterized by their high temperatures and luminosities. This region contains several young, hot stars that are responsible for the intense ultraviolet radiation that influences the surrounding interstellar medium. The stars in Scorpius OB2 are relatively young, with ages ranging from a few million to about 10 million years. This association is significant for studying stellar evolution and the dynamics of star formation, as it provides insights into how massive stars interact with their environment and contribute to the chemical enrichment of the galaxy.
