Large galaxy that's globular in shape, the closer to the center you get the brighter and whiter the image due to the amount of stars. Stars are everywhere in this image, of all sorts of colors.

M53 – Hubble Messier 53

Thousands and thousands of brilliant stars make up the globular cluster Messier 53, captured with crystal clarity in this image from Hubble. Bound tightly by gravity, the cluster is roughly spherical and becomes denser toward its heart. This image is a composite of multiple images taken in visible and infrared wavelengths of light.
