Thousands of bright stars fill a spherically shaped globular cluster. In the center, most of the stars appear blue. The globular cluster’s bright blue-white core is surrounded by a thick shell of yellower stars, seen in differing sizes according to their position in the spherical star cluster. They spread out beyond the edges of the image, appearing smaller and sparser at the corners of the image. A distant spiral galaxy is also visible in the lower-left corner of the image.
