Using data from the orbiting Infrared Astronomical Satellite (IRAS), astronomers at the University of Michigan at Ann Arbor discovered several dim galaxies in an area of the universe previously believed to be devoid of large celestial objects. The discovery of seven dim galaxies in the "Bootes Void" challenges accepted theories of the structure of the universe, which is believed to consist of filaments or "bubbles" of matter surrounding less dense areas of relatively empty space. The Michigan astronomers said they planned to continue studying IRAS's infrared data in hopes of finding more dim galaxies. (W Post, Jan 16/89)
