This image of the first-ever foreground quasar (blue) lensing a background galaxy (red) was taken with the Keck II telescope and its NIRC-2 instrument using laser guide star adaptive optics. Discovering more of these lenses will allow astronomers to determine the masses of quasars’ host galaxies. Credit: F. Courbin, G. Meylan, S. G. Djorgovski, et […]

Like a raindrop forming in a cloud, a star forms in a diffuse gas cloud in deep space. As the star grows, its gravitational pull draws in dust and gas from the surrounding molecular cloud to form a swirling “protoplanetary disk.” This disk eventually further consolidates to form planets, moons, asteroids and comets.

If you think washing the mirrors and windows in your home is a daunting task, imagine cleaning two of the largest light-collecting surfaces in the astronomy world—the twin 10-meter Keck telescope mirrors. Keck Observatory’s two primary mirrors are each comprised of 36 hexagonal segments. Each segment is 1.8 meters, or 6 feet, in diameter, weighs […]

University of Hawaiʻi photographer R. David Beales won Best in Show at the University Photographers Association of America, or UPAA, competition for his December 2009 image “Mauna Kea Summit,” which features the W. M. Keck Observatory’s laser piercing the Hawaiian night sky. The Observatory was the first large telescope to apply adaptive optics for obtaining […]
