The heart of a globular cluster, like Terzan 4, is packed with stars so tightly that individual stars are difficult to distinguish from one another, especially with ground-based telescopes.

Astronomers spent a decade compiling this special image with the Hubble Space Telescope and then stitched together 600 photos to showcase over 200 million stars.

The more distant the star is, the fainter it appears. Hubble worked hard, taking images of spiral nebulae every clear night and looking for the telltale variations of Cepheid variables. By the end of ...
