Gravitational lensing provides unique insights into astrophysics and cosmology. Using ESO’s Very Large Telescope, astronomers have discovered a new strong...

Dai et al used Chandra to measure the spin of five quasars. Gravitational lensing of the light from each of these black holes by an intervening galaxy has created multiple images of each quasar, as shown by these Chandra images of four of the targets.

By combining the capability of NASA’s Chandra X-ray Observatory with the power of a natural phenomenon called gravitational lensing, a team of astronomers...

This image shows four different images of SN Refsdal whose light has been distorted and magnified by the massive galaxy cluster MACS J1149+2223 in front of it. The huge mass of the cluster and one of the galaxies within it is bending the light from a supernova behind them and creating four separate images of the supernova. The light has been magnified and distorted due to gravitational lensing and as a result the images are arranged around the elliptical galaxy in a formation known as an Einstein cross.
