Three ancient globular clusters found in the galactic bulge

Three old and metal-poor globular clusters have been spotted in the Milky Way's bulge. The newly found clusters, designated Camargo 1107, 1108 and 1109, could offer important clues on structure and nature of the central region ...

Spitzer captures stellar family portrait

In this large celestial mosaic taken by NASA's Spitzer Space Telescope, there's a lot to see, including multiple clusters of stars born from the same dense clumps of gas and dust. Some of these clusters are older than others ...
