...gorgeous red object against the silver gray of the Large Magellanic Cloud," said Robert Garrison of the University of Toronto. Ever since it burst into view in the southern hemisphere on Feb. 23, Supernova 1987A, the brightest exploding star in 383 years, has fascinated astronomers and astrophysicists. Its surprising behavior has prompted them to rethink how massive stars evolve and what forces rage within them. "This is how science is done," said an exultant Garrison. "There is discovery, then wild speculation, then a settling of accounts...
...star that exploded to create Supernova 1987A has been identified as Sanduleak-69 202, a blue supergiant whose position in the Large Magellanic Cloud neatly coincided with the supernova. Though Sanduleak was suspected, some astronomers, like Harvard's Robert Kirshner, at first thought that satellite data on the LMC showed the star still existed after the blast and thus could not have been the progenitor. Later other scientists examining the same evidence failed to locate SK-69 202. Admitted Kirshner last week: "It was that star that blew up -- no matter what you've heard elsewhere . . . from me." His colleagues...
...again, peaking around May 22, when it was easily visible to the naked eye. Since then it has been gradually dimming. One possible explanation was proposed by Astronomer Stan Woosley of the University of California at Santa Cruz. He suggests that the decay of radioactive elements within 1987A's cloud of debris is now generating the light. If he is right, gamma-ray emissions from decaying cobalt 56 should start showing up this summer. Concedes Woosley: "I'm out on a limb." A more radical theory, put forth by Princeton Astrophysicist Jeremiah Ostriker, proposes that the neutron star that formed...
