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. ... The intensity and spectral energy distribution of the emission suggest a dust mass of about 0.4 to 0.7 times the mass of the Sun. ... Our observations imply that supernovae can produce the large dust masses detected in young galaxies at very high redshifts. ... ADS Citation Query . ...
