Tuesday, May 31, 2011: This Hubble photo shows globular cluster Terzan 5, which possesses an exceptionally dense core. As a result, scientists think that it has one of the highest stellar collision rates for a globular cluster. While packed in at such close quarters, many stars push so close together that they form tight binary systems.
