Using NASA's Hubble Space Telescope (HST), an international team of astronomers took a major step in redetermining the expansion rate of the universe. This rate, known as the Hubble Constant, is one of two critical numbers needed for making a precise determination of the size and age of the universe. The Constant is an estimate of the rate at which the universe is expanding and is expressed in kilometers per second per megaparsec (3.26 million light years). The results were reported by Drs. F Duccio Macchetto, Nino Panagia, and Abhijit Saha of the Space Telescope Science Institute, Baltimore, Maryland; Allan Sandage of the Carnegie Institution of Washington; and Gustav Tammann of the University of Basel, Switzerland, at the international workshop "Science with the Hubble Space Telescope," held in Sardinia, Italy, June 29 through July 9, 1992.

NASA reported that a survey of the heavens with the Hubble Space Telescope (HST) was uncovering remote and unusual galaxies never before resolved by optical telescopes on Earth. HST revealed an unusual variety of shapes and structures in these distant galaxies, which previously had appeared as fuzzy blobs in ground-based sky surveys. The results might lead to much clearer understanding of the formation and evolution of galaxies. The results were presented by Dr. Richard Griffiths of the Space Telescope Science Institute, Baltimore, Maryland. (NASA Release 92-98)
