Building the Mighty Keck Observatory – Credit: JPL

Please be patient while video loads:

In 1985, construction began on what was to become, and still remain, the biggest optical/infrared telescopes on Earth. Since first science in 1993 for Keck I and 1996 for Keck II, the two telescopes are the most scientifically productive telescopes on Earth, publishing more papers per telescope than any of its peers.
