Cosmic Lens MACS J1720+35 Helps Hubble to Find a Distant Supernova (image) ESA/Hubble Information Centre Share Print E-Mail Caption The heart of a vast cluster of galaxies called MACSJ1720+35 is shown in this image, taken in visible and near-infrared light by the NASA/ESA Hubble Space Telescope. The galaxy cluster is so massive that its gravity distorts, brightens, and magnifies light from more distant objects behind it, an effect called gravitational lensing. In the top right an exploding star nicknamed Caracalla and located behind the cluster can just be made out. Credit NASA, ESA, S. Perlmutter (UC Berkeley, LBNL), A. Koekemoer (STScI), M.
