Exploring the local and distant Universe from the world’s largest and most scientifically productive telescopes on Earth.

From Hawaii’s Maunakea, astronomers around the world use W. M. Keck Observatory to observe the universe with unprecedented power and precision. The twin Keck Observatory telescopes are the world’s most scientifically productive optical and infrared telescopes.

Step inside our telescope facility and check out one of our twin telescopes, Keck I, in the viewing area marked by a blue door. You may also peruse through gallery exhibits to learn about Keck Observatory’s research and operations.

Keck I and Keck II Telescopes. The twin W. M. Keck Observatory telescopes are the world’s most scientifically productive optical and infrared ground-based telescopes. Each telescope operates with nanometer precision.

Assistants operate the telescopes at the summit while astronomers gather data via remote observing from observatory headquarters in Waimea. The W. M. Keck Observatory was the first facility on Mauna Kea to use remote observing.

Stay connected with the very latest astronomical research that our Maunakea Observatories community is conducting here in Hawaiʻi! We’ve launched a series of Maunakea Observatories Science Talks, which you may watch by visiting:

Jan 13, 2006 · The ‘OHANA (Optical Hawaiian Array for Nanoradian Astronomy) array, or “interferometer,” will provide ultra-high resolution images of the near-infrared universe, 80 times more accurate than a single 10-meter Keck telescope.

Nov 24, 2015 · From brilliant design, sheer grit, and less than 6 percent of what the Hubble Space Telescope cost, the W. M. Keck Observatory was born and has since remained home to the two biggest and most scientifically productive telescopes on Earth.
