Cosmic Coincidence

A distant quasar accidentally appears on the sky behind a nearby galaxy (in blue). Following Einstein's law for focusing light, the galaxy images by gravity the quasar into four distinct components (the outer bright white points surrounding the inner, white, center of the galaxy). Data obtained with NASA's Hubble Space Telescope and processed by John Bahcall, David Saxe, and Donald Schneider while at Institute for Advanced Study.
