A globular cluster typically has only one ancient star population. New data from the NASA/ESA/CSA James Webb Space Telescope and the NASA/ESA Hubble Space Telescope not only confirm the existence of two distinct populations of stars in the ancient stellar system Terzan 5, once classified as a globular cluster, but also provides evidence for two more recent rounds of star formation. This Webb/NIRCam image shows the star cluster Terzan 5. Image credit:...
