The NASA/ESA Hubble Space Telescope offers a delightful view of the crowded stellar encampment called Messier 68, a spherical, star-filled region of space known as a globular cluster. Mutual gravitational attraction amongst a cluster's hundreds of thousands or even millions of stars keeps stellar members in check, allowing globular clusters to hang together for many billions of years.
