Cosmic Beacons Reveal Milky Way’s ancient Core

The plane of our Galaxy as seen in infrared light from the WISE satellite. The bulge is a distinct component and most of its mass resides in a boxy/peanut bulge, which is in cylindrical rotation. An ancient population, estimated to be 1% of the mass of the bulge, has been detected kinematically detected in the inner Milky Way and does not cylindrically. Instead, this population is likely to have been one of the first parts of the Milky Way to form. Credit: NOAO/AURA/NSF/AIP/A. Kunder

An international team has discovered that the central 2000 light years within the Milky Way Galaxy hosts an ancient population of stars >10 billion years old and their orbits in space preserve the early history of the formation of the Milky Way...
