Astronomical observatory located southwest of Tucson, Ariz.

Mouʹnə kāʹə, astronomical observatory complex located on Mauna Kea peak, the "white mountain" on the island of Hawaii, at an altitude of more than 13,600 ft (4,145 m). Because of its height and excellent seeing, this site supports by far the largest astronomical facility in the world.

Astronomical observatory located in California on Mt. Wilson, near Pasadena. Mt. Wilson Observatory was founded in 1904 by George E. Hale. Its equipment includes 100-in. (2.5-m) and 60-in. (1.50-m) reflecting telescopes and two solar-tower telescopes.

Federal observatory for radio astronomy, founded in 1956 and operated under contract with the National Science Foundation by Associated Universities, Inc., a group of major universities. The headquarters are at Charlottesville, Va.; the original observatory site is in Greenbank, W.Va.

Spacecraft launched from the space shuttle Atlantis on 18 October 1989 to explore the planet Jupiter. Galileo's probe entered the atmosphere of Jupiter in December 1995. It radioed information back to the orbiter for 57 minutes before the craft was destroyed by atmospheric pressure.

An optical telescope launched into orbit around the Earth in 1990 in the space shuttle Discovery, allowing observation of a volume of the universe 350 times as large as that observable from Earth.

From Collins Dictionary of Astronomy
A next-generation space observatory optimized for infrared astronomy that NASA plans to launch in August 2011 as the successor to the Hubble Space Telescope.

From Collins Dictionary of Astronomy
Two NASA robotic roving landers named Spirit and Opportunity, launched to Mars in summer 2003 from Cape Canaveral, Florida, by Delta 2 rockets. Spirit was launched on June 10, followed by Opportunity on July 7.
