W
Overview
Operates two 10-meter optical/infrared telescopes on Maunakea with imagers, spectrographs, and laser guide star adaptive optics. Light from space is collected and processed by its instruments to produce images and spectra; the adaptive optics system sharpens images by correcting atmospheric distortion in real time. It stands out as a nonprofit scientific partnership among Caltech, the University of California, and NASA, funded by the W. M. Keck Foundation, with access for a broad astronomy community. Its goal is to enable astronomical discovery by providing premier observing facilities and advanced instruments for research.
