Caption
The twin 10-meter Keck Observatory telescopes are the most scientifically productive optical and infrared telescopes on Earth. Located on Maunakea, Hawaii, the observatory works closely with several of NASA's observatories. Pictured here (not to scale) from the top, going clockwise, are the James Webb Space Telescope (not yet launched), Hubble Space Telescope, Chandra X-ray Observatory, and Spitzer Space Telescope.
