The innovative Hobby-Eberly Telescope was dedicated. It uses a mosaic of 91 individual mirror segments to create a primary mirror with an effective light-gathering power of a single 9.2-meter mirror.
NASA launches Hubble Space Telescope, which was developed and planned with the input of several University of Texas astronomers and engineers. In particular, Fritz Benedict and Bill Jeffreys led a team developing the telescope's Fine Guidance Sensors, which allow it to point precisely at cosmic targets. Today, McDonald astronomers routinely use Hubble and other space-based telescopes in their research.
Dedication of the 107-inch (2.7-meter) Telescope. It was later renamed the Harlan J. Smith Telescope in honor of the observtory director responsible for its construction.
