This Hubble Space Telescope image of SN 1987A shows a fished-shaped central
blob of supernova debris that has begun to brighten. This brightening, due to illumination by X-rays from the surrounding ring of pre-supernova material, marks the shift from a supernova to supernova remnant. The closest supernova explosion seen in almost 400 years, SN 1987A is located in the Large Magellanic Cloud.
