Astronomers observe four images of the same supernova using a cosmic lens

Astronomers have for the first time observed a supernova (an exploding star) multiply-imaged due to gravitational lensing. The light from the supernova is seen in four different images due to a cosmic phenomenon that causes light to be deflected by the gravity of a massive galaxy. This effect creates four separate images of the same supernova. The discovery is published in the scientific magazine Science in a special issue celebrating the centenary of Einstein’s Theory of General Relativity.
