About W. M. Keck Observatory
The twin Keck Observatory telescopes are the world’s most scientifically productive optical and infrared telescopes. Each telescope weighs 300 tons and operates 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. Keck Observatory is a 501(c)3 supported by both public funding sources and private philanthropy.
W. M. Keck Observatory takes its responsibility for good stewardship of Maunakea very seriously. That’s why we are deeply committed to full transparency for our staff and our community as we work to understand how, why, and to what extent a small amount of hydraulic fluid has been seeping from our hydraulic system at our Maunakea facility.
