HUBBLE CAPTURES A "FIVE-STAR" RATED GRAVITATIONAL LENS

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.
