Globular Cluster Terzan 2

Terzan 2 is a globular cluster in the constellation Scorpio. Globular clusters are stable, tightly gravitationally bound clusters of tens of thousands to millions of stars found in a wide variety of galaxies. The intense gravitational attraction between the closely packed stars gives globular clusters a regular, spherical shape. As a result, images of the hearts of globular clusters, such as this Hubble Space Telescope observation of Terzan 2, are crowded with a multitude of glittering stars.
