Multiple images of a supernova from far, far away and long, long ago
For the first time, a single supernova explosion has been seen split into multiple images by the gravitational lens deflections of intervening masses. In this case the masses are a large galaxy and its home galaxy cluster.
The featured image was captured last November by the Earth-orbiting Hubble Space Telescope.
The yellow-hued quadruply-imaged Supernova Refsdal occurred in the early universe far behind the cluster.
