Astronomers at the Harvard-Smithsonian Center for Astrophysics announced the discovery of the largest structure seen so far in the universe. The scientists claimed to have discovered a sheet of galaxies 500 million light-years long, 200 million light years wide, and about 15 million light years thick, which they are calling the "Great Wall". The Great Wall, which is invisible to the naked eye, was estimated to be 200 million to 300 million light-years away from Earth and was expected to reveal new insights on the distribution of matter in the universe.

The Colorado-based Energetics Satellite Corporation announced that it had completed an agreement with the Soviet Union's civilian space agency, Glavkosmos, to launch two U.S.-built commercial satellites on Soviet boosters. The contract provided for the launching of two geosynchronous satellites at a cost of $6.5 million each, with an option to add six more satellite launches in the future. The total potential value of the agreement was $54 million for the eight-satellite launch option. (W Post, Nov 16/89; NY Times, Nov 17/89)
