Astronomers detect long-sought compact object within the remnant of Supernova 1987A.
In February 1987, the closest supernova to earth in almost 400 years exploded onto the scene. Designated Supernova 1987A (SN 1987A), it resulted from the death of a massive star in the Large Magellanic Cloud, a dwarf galaxy 160,000 light-years away. In the decades since, its remnant has been studied by telescopes at all wavelengths of light from X-rays to radio. Yet despite all the scrutiny, one mystery has remained.
Theory predicted that the stellar explosion should have produced either a neutron star or a black hole. Evidence for such a compact object has long been sought, without success. Now, new observations by NASA’s James Webb Space Telescope have provided the first direct evidence of what is likely a neutron star, revealed by the effects of its high-energy emission.
