The Explosion Cloud from SN 1987A
On February 23, 1987 the star Sanduleak -69 202 exploded in the Large Magellanic Cloud. The explosion was accompanied by the emission of hard X-rays and Gamma-rays. But in contrast, no soft X-ray emission, expected from a pulsar or a shock wave heated environment, was seen. Measurements using an X-ray detector onboard a sounding rocket of the MPE in August 1987 failed to detect soft X-rays, as did the first ROSAT observations, which, however, confirmed that the exploding star was a blue giant. Not until the middle of 1991 did ROSAT register the first soft X-rays of that explosion. The explosion cloud from SN 1987A, surrounded by a row of another supernova remnants and stars, is indicated in the image by the cross-hairs.
