Field is filled with white stars, smattered with blue-white and reddish-orange stars. Stars are concentrated at the center of the image. All are on a black background.

Hubble Messier 55

This image shows just a portion of M55, the cluster as a whole appears spherical because the stars’ intense gravitational attraction pulls them together. Hubble’s clear view above Earth’s atmosphere resolves individual stars in this cluster. Ground-based telescopes can also resolve individual stars in M55, but fewer stars are visible.
