Number 181 (Story #3), June 3, 1994 by Phillip F. Schewe and Ben Stein TWO LARGE RINGS LOOMING MYSTERIOUSLY NEAR , but not exactly around, Supernova 1987A have been imaged by the Hubble Space Telescope. One ring stands in front and the other in back of the supernova in the new pictures. Together with a much-studied inner ring centered on the supernova, the three-ring structure resembles a gigantic hourglass. A settled explanation for this bizarre configuration never seen before around a supernova will come only with additional observations. (Science News, 28 May 1994.)
