Hubble's Best Gravitational Lens

Tue, 23 May 2006 - The most powerful telescopes in the Universe are relatively nearby galaxies, which warp and focus the light of more distant objects. Called gravitation lenses, which occur randomly, are a boon for astronomers as they allow powerful telescopes, like Hubble, to look even further out into the Universe. This Hubble image is the first "quintuple quasar" ever seen, where an entire galaxy perfectly focuses a more distant quasar - located 12 billion light-years away.
