Oldest Stars

Caption

Distribution of the oldest stars in our galaxy (upper panel) compared with the full population of primordial stars (lower panel). While the oldest stars are all located near the center, where they are very difficult to detect, later forming stars made of gas without heavy elements should be located throughout the galaxy. The fact that no such stars have ever been detected places important scientific constraints on the properties and formation of these stars. Background image from DIRBE data, (c) Edward L. Wright
