Gravitational lensing Rich strong lensing cluster from RCS2 at z=0.7
Gravitational lensing Strong gravitational lensing requires a good alignment of the source and the lens. This doesn’t happen often... The light rays of all objects are perturbed, but the effect is usually just too subtle to see: an (unknown) shift in position a small distortion of the shapes of the galaxies
