Orion OB1 association

The Orion OB1 association is a group of young, massive stars located in the constellation Orion. These stars formed from the same giant cloud of gas and dust and are still relatively close to each other in space. The "OB" designation indicates they are hot, luminous stars of spectral types O and B. This association is important for understanding stellar formation and evolution because it contains many young stars and stellar remnants, providing insights into how stars develop within their birth regions. It is part of the larger Orion Molecular Cloud Complex, one of the most active star-forming areas in our galaxy.
