Caption

Discovery spectrum (insert upper right) showing water maser emission from the quasar MG J0414+0534 with high redshift. The background image, an HST near infrared image of the quasar, shows how the quasar appears broken up into four components by a foreground galaxy (diffuse source in the center), acting as a gravitational lens and strengthening the signal by a factor of 35. The inset (lower right) with galaxy M87 shows how the quasar could be seen from nearby..
