STScI Scientists Surprised to Find Brightness ‘Gap’ in Ancient Star Cluster

June 03, 2026

$This astronomical image is speckled with thousands of stars against the black background of space. Most stars are visible only as white pinpoints. The great majority of stars are crowding the image’s center, which appears as an irregular round shape. Most stars in the center of this cluster are whiter, and those along periphery edges yellower.
