Soviet and Japanese scientists confirmed the first positive detection of x-rays from an exploding supernova. Soviet scientists, using x-ray telescopes aboard the Soviet astrophysics module Kvant, made the detection on August 10, 1987. Japanese scientists, using smaller x-ray instruments aboard their Ginga satellite, first observed the x-rays from the supernova on August 15, 1987. (W Post, Oct 4/87)
