The hottest and most massive stars don't live long enough to disperse throughout the galaxy. Instead, they can be found near the clouds of gas and dust where they formed -- and where they will explode as supernovae after a few million years. They huddle in tight clusters with other young stars or in looser groupings called OB associations, a name reflecting their impressive populations of rare O- and B-type stars.
