KeckWatch is brought to you by the W. M. Keck Observatory, which operates the two largest optical/infrared telescopes on Earth from nearly 14,000 feet on Maunakea in Hawaii. Since first science in 1993, they have become the two most scientifically productive telescopes on Earth.

With KeckWatch, you can share in our discoveries. Sporting thousands of stars, all 8 planets, galaxies, nebula and star clusters, along with Hawaiian star names, status updates, and news from Keck Observatory, you’ll learn where Hokupa’a (Polaris) might be, or what planet was shimmering above the house last night.

Maunakea, the home of the Keck Observatory telescopes, has special cultural significance to the Hawaiian people and is the premier location on Earth for astronomy research. Keck Observatory’s work studying the stars advances the kind of scientific curiosity that has always been a part of Hawai‘i’s cultural heritage, from the celestial navigators of ancient Hawai‘i to today. We invite you to become a part of our observatory, viewing the stars alongside the world’s greatest astronomers at W. M. Keck Observatory.
