STScI The Vault

The Space Telescope Science Institute, in Baltimore, Md., selects observing proposals, plans observations, retrieves and archives Hubble data, and makes the information available to the public. In this photo you see astronomers at the Space Telescope Science Institute anxiously awaiting results from the impact of Comet Shoemaker-Levy 9 with the planet Jupiter in July 1994.

Each year astronomers from dozens of countries submit proposals to the institute. An international panel of scientists judges them on a list of criteria, selecting the best. Typically, the institute receives more than 1,000 proposals a year and selects about 300.

The data from Hubble's observations are sent to Earth by way of a NASA relay satellite. The data are then forwarded to the institute, where they are analyzed and stored. Observers may then study the data at the institute or from a remote location.
