Astronomers have made a stunning discovery of the closest known ultraluminous supernova to date. Located in the constellation of Pegasus, the supernova is approximately 200 million light years away from us, making it one of the most nearby ultraluminous supernovae seen to date. The supernova, which is classified as a Type Ia, is about 10 times brighter than a typical supernova of its type. Scientists have been able to observe the supernova in great detail, which provides valuable insight into the properties of ultraluminous supernovae and how they may differ from typical supernovae.
