This heated halo, called the circumgalactic medium (CGM), was the incubator for the Milky Way’s formation some 10 billion years ago and could be where basic matter unaccounted for since the birth of the universe may reside. A star’s position in and motion through our Galaxy, for example, can tell us in what portion of the Galaxy it was born (e.g. In a nearby spiral arm of the Milky Way, more than 1000 light years away from our solar system’s present position, lies the Orion nebula, a birthplace of giant stars. 2012), these robust ages allow us to order the early sequence of events that shaped our Galaxy, identifying the red-sequence as the first stars formed within the Milky Way progenitor which, because of their kinematics, can be described as its long sought in-situ halo.
