#Euclid #telescope captures #EinsteinRing revealing warping of #space, showing light from a distant #galaxy bent into a perfect circle by the gravity of another galaxy sitting between Earth and the source, #ESA said.
Phenomenon, spotted around galaxy #NGC6505 some 590M light-years from Earth, reveals the warping of space predicted by Einstein's theory of relativity. The background galaxy, located 4.42B light-years away, appears as a complete ring of light around NGC 6505.

[Un anneau parfait ...] L'analyse des tous premiers clichés acquis par le #télescope spatial #Euclid a révélé cet anneau d'Einstein parfaitement circulaire. Exceptionnel ! Rarissime !

Cet anneau encercle une #galaxie (NGC 6505) située à quelque 590 millions d'années lumière de la Terre. Il est constitué de la #lumière provenant d'une galaxie plus lointaine et brillante - une galaxie jusque là inconnue, distante de 4,42 milliards d'années lumière.

Cette galaxie est donc la toute première découverte de la mission @ec_euclid ! Une découverte qui en augure bien d'autres ... Good luck, Euclid !

One of the coolest, most trippy deep-space object is called an Einstein ring. Named for Albert Einstein, who predicted that massive objects in space could magnify or lens the light of objects far behind them, the eerily perfect circle is an illusion created by warped space-time.
