The 15 pages that link to W. M. Keck Observatory, each with the reason it gives.

• Infrared astronomyRelated: Its large apertures and adaptive optics enable detailed ground-based infrared observations.

• California Institute of TechnologyRelated: Caltech is a partner in the observatory and uses its telescopes for research.

• Very Large TelescopeCompared with: Keck uses two larger individual mirrors, rather than four 8.2-meter Unit Telescopes.

• Thirty Meter TelescopeRelated: Keck’s segmented-mirror success helped establish the engineering path toward a much larger telescope.

• Mauna KeaBroader topic: Its twin telescopes are among the largest instruments operating on the summit.

• Large Binocular TelescopeCompared with: Keck uses segmented primaries, whereas the Large Binocular Telescope has two single 8.4-meter mirrors.

• Altazimuth mountBroader topic: The Keck telescopes demonstrate how altazimuth mounts support very large instruments.

• Active opticsBroader topic: Its segmented mirrors use active control to maintain alignment and optical figure.

• Reinhard GenzelRelated: Independent observations there helped confirm the Galactic-center results.

• Subaru TelescopeCompared with: Keck shares Subaru’s site but uses larger segmented mirrors and different observing strengths.

• Ritchey–Chrétien telescopeBroader topic: The Keck telescopes use Ritchey–Chrétien optical layouts.

• Giant Magellan TelescopeCompared with: Keck pioneered large segmented mirrors on a smaller scale than the Giant Magellan Telescope.

• Andrea M. GhezRelated: Its telescopes supplied much of the high-resolution data behind Ghez’s Galactic Center research.

• Maunakea ObservatoriesBroader topic: Its large segmented mirrors support detailed studies of distant galaxies, stars, and planets.

• Sandra FaberRelated: Faber’s work with Keck enabled detailed observations of distant galaxies and their evolution.
