... We report far-infrared and submillimeter observations of supernova 1987A, the star whose explosion was observed on 23 February 1987 in the Large Magellanic Cloud, a galaxy located 160,000 light years away. ...
... Many of the best candidates have, surprisingly, not been found near main sequence stars, but around pulsars, the spinning, magnetized neutron star remnants of supernova explosions. ...
... For example, PSA was used to measure the diameter of the debris from the explosion of SN1987a (Karovska et al. 1991) and estimate the asymmetry in the envelope (Papaliolios et al. 1989) from speckle data recorded over a three year period. ...
... Stellar-mass black holes form when a heavy star collapses under its own weight in a supernova explosion, and have been identified in X-ray binaries. ...
