Writing in the journal Nature, U.S. scientist Walter We said that his team had taken pictures of a so-called nuclear accretion disk, which scientists have long theorized surrounds a black hole. The idea is that matter swirls around the black hole as it is being pulled in, forming an accretion disk, a flat ellipse resembling a round Danish pastry. The disk was discovered through use of the planetary camera on the Hubble Space Telescope. (RTW, Jul 14/93)
NASA began the countdown for the planned weekend launch of Space Shuttle Discovery on a satellite-delivery and spacewalking mission. During the nine-day mission, the astronauts were to release an experimental communications satellite des-tined for a 22,300-mile-high orbit and an ultraviolet telescope to be retrieved six days later and returned to Earth. They also planned to test new navigation equipment and conduct a spacewalk to try out tools needed for the Hubble Space Telescope repair mission in December.
