From atop Maunakea on the Island of Hawaii, 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 most scientifically productive optical and infrared telescopes on Earth and operate with nanometer precision. The telescopes’ primary mirrors are 10-meters in diameter and are each composed of 36 hexagonal segments that work in concert as a single piece of reflective glass. Both telescopes feature a suite of advanced instruments including imagers, multi-object spectrographs, high-resolution spectrographs, integral-field spectrometers, and world-leading laser guide star adaptive optics systems.

Keck Observatory is a private 501(c) 3 non-profit organization operated as a scientific partnership among the California Institute of Technology, the University of California, and the National Aeronautics and Space Administration. The Observatory was made possible by the generous financial support of the W. M. Keck Foundation.
