A team of astronomers reported that they had discovered evidence of "brown dwarfs", large celestial objects that are intermediate in size between planets and stars. The findings, presented at a meeting of the American Astronomical Society, showed evidence of at least nine brown dwarfs orbiting stars in the constellation Taurus. The observed objects were believed to be from 5 to 20 times the size of Jupiter. Evidence of brown dwarfs was expected to help account for some of the "missing dark matter believed to exist in the universe. (W Post, Jun 15/89; P Inq, Jun 25/89)
