Hubble Captures a "Five-Star" Rated Gravitational Lens

May 23, 2006: NASA's Hubble Space Telescope has captured the first-ever picture of a group of five star-like images of a single distant quasar.

The multiple-image effect seen in the Hubble picture is produced by a process called gravitational lensing, in which the gravitational field of a massive object in this case, a cluster of galaxies bends and amplifies light from an object in this case, a quasar farther behind it.
