Number 28 (Story #4), April 4, 1991 by Phillip F. Schewe and Ben Stein A STREAMER OF GAS AT THE GALACTIC CENTER , connecting a ring of material surrounding the galactic nucleus at a distance of 2 parsecs with molecular clouds lying at a distance of 10-20 parsecs, has been recorded by a Harvard-MIT-Boston-Naval Observatory team of astronomers using the Very Large Array radio telescope. They believe that the material in the outer clouds may be impelled by nearby supernovas toward the inner ring which, in turn, fuels activity (perhaps a black hole) at the galactic center.
