The twin 10-meter Keck Telescopes are the most powerful tools we have to study the cosmos.

In addition to offering the two largest light collection mirrors on the planet, the Keck telescopes host a suite of state-of-the-art observing instruments and adaptive optics capabilities to collect and analyze astronomical data with unprecedented precision and clarity.

Keck Observatory’s legacy of exploration has contributed to all areas of astronomy and astrophysics - the discovery of exoplanets; the study of how planets, stars and galaxies form; the nature of black holes; and the chemical composition and evolution of the Universe.
