...Hubble Space Telescope, which will belaunched via shuttle in February 1990, will allowastronomers to see objects in better detail thanbefore, according to Professor of Astronomy RobertP. Kirshner...
...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...
...Kirshner, who has already travelled to NASA's Goddard Space Flight Center several times to collect data from a UV-detecting satellite, said he hopes to discover evidence which would support current theories on supernova evolution...
Supernova can also be used to measure the size and age of the universe, Kirshner said...
...When a massive star's core collapses in a supernova, the energy is partially emitted in neutrinos [according totheory]," Kirshner said. Although this idea hasbeen written about in astronomy texts for years,"now, we have actually observed [the particles],"he said...
