The Hubble Telescope captured the remnants of the cosmic catastrophe

A picture from NASA/ESA’s Hubble Space Telescope shows the remains of a supernova – a huge explosion that marks the end of the life of a dying star. This cosmic object – known as DEM l249 – is thought to have been produced by a type 1A supernova during the death of a white dwarf. Although white dwarfs are usually stable, if they are part of a binary system, they can slowly accumulate matter.
