Steward Observatory

(stew -erd) The observatory of the University of Arizona at Tucson, whose main instruments are at the Kitt Peak National Observatory, including a 2.3-meter reflector. A number of telescopes are under construction or at the design stage at the Steward Observatory. Of these, one of the most important is the Large Binocular Telescope (LBT), due to become operational on Mount Graham, Arizona, in 2005. Equipped with twin 8.4-meter lightweight honeycomb mirrors sitting on the same mount and fitted with adaptive optics, the LBT will arguably be the most advanced groundbased telescope in the world. Its configuration will provide an effective aperture of 22 meters, enabling it to be used in the search for Earth-sized extrasolar planets. The Steward Observatory Mirror Laboratory operates at the forefront of optical technology. It cast and polished the new 6.5-meter mirror that replaced the smaller mirrors of the Multiple Mirror Telescope, operated jointly by the University and the Smithsonian Astrophysical Observatory. The Steward Observatory has also participated in several current and planned NASA space observatories, for example by making components for the Hubble Space Telescope, the Spitzer Space Telescope, and the James Webb Space Telescope.

The University of Arizona's Steward Observatory has partnered with the Catalina Sky Survey, which searches for near-Earth asteroids from atop Mount Lemmon, in an effort dubbed Searches after Gravitational Waves Using ARizona Observatories, or SAGUARO, to find optical counterparts to massive mergers.
The young planet is still slowly accumulating material, but new observations with the 6.5-m Magellan Clay Telescope, to be published in Astrophysical Journal Letters by Kevin Wagner (Steward Observatory) and colleagues, show that it has probably already acquired most of its gas.

Jared Males, a NASA Sagan Fellow in the UA's Department of Astronomy and Steward Observatory, claimed that it was an important next step in the search for what was termed "exoplanets." He also said that imaging in visible light instead of infrared is what they need to detect planets that can harbor life.
Lead author Jared Males, a NASA Sagan Fellow in the UA's Department of Astronomy and Steward Observatory, said that this is an important next step in the search for exoplanets because imaging in visible light instead of infrared is what we likely have to do if we want to detect planets that might be suitable for harboring life.
