lens, gravitationalObject in space which, by its gravitational field, bends light in a similar way to a spectacle lens. As a result of this, one object, such as a quasar, can appear as multiple images. A gravitational lens also produces a magnifying effect. Numerous examples are now known of such multiple imaging. Images of quasars and galaxies are also stretched into arcs by gravitational lenses. |

| The Hubble Space Telescope captures a bevy of curvy galaxies 13 billion light-years, distorted by a gravitational lens. The cluster's enormous mass acts as a gravitational lens, magnifying, brightening, and distorting images of more-distant galaxies. The researchers accomplished their feat without the aid of a so-called gravitational lens, an intervening duster of galaxies whose mass boosts the light of distant objects On its way to earthly observers. |
