Gravitational lensing

Référence de la vidéo 11927232
Annotated view of gravitationally lenses objects in the distant galaxy cluster SDSS J1004+4112. A distant quasar much further away than the cluster has had its light lensed into five separate images, which are highlighted first. Three images of a distant lensed galaxy are then marked, and then a supernova in one of the cluster galaxies is ringed. Gravitational lensing is the bending of light by a powerful gravitational field, which makes objects appear in several different places as light travelling in different directions from them is bent back towards the viewer. The lensing cluster here is some seven billion light years from Earth, the quasar is around ten billion light years from Earth. Image taken by the Hubble Space Telescope.
