Magnified Supernova iPTF16geu Seen by Keck

Caption

This is an image of the gravitationally lensed iPTF16geu Type Ia supernova taken in near-infrared with the W.M. Keck Observatory. The lensing galaxy visible in the center has distorted and bent the light from iPTF16geu, which is behind it, to produce multiple images of the same supernova (seen around the central galaxy). The position, size and brightness of these images help astronomers infer the properties of the lensing galaxy.
