Each 10-meter main mirror is but a single part of a magnificent ... [Andrew] bit the bullet and rebuilt the obsolete boards from scratch. The Keck telescopes were built over three decades ago ...

The ability to retrofit the current Keck secondary mirror with a higher-density 3000-4000 actuator ... Northern Hemisphere location atop Maunkea Hawaii. Picture 1: Twin telescopes Keck I and Keck 2 ...

It Will Be Much, Much Slower The Keck Observatory's two telescopes are nothing short of engineering marvels, each featuring a 32-foot-wide (10-meter) primary mirror comprising 36 precisely aligned ...

A further grant of US$1.3 million is allowing scientists to design a centre-launch laser telescope that will be installed behind the secondary mirror of the Keck II. Light from the laser is ...

Earlier this year a simple indicator LED brought the Keck 1 telescope, a 370 tons mass, to a halting stop. How exactly did an LED do this? Simple: it did nothing. As it so happens, [Andrew Cooper ...

M. Keck Observatory, Automated Planet Finder, and Gemini North telescopes. Of course, adaptive optics requires more than just deformable mirrors. Other key components, such as wavefront sensors, laser ...

Segmented mirrors, such as those used on the Keck and Gran Telescopio Canarias telescopes, are much easier to produce and transport, are not subject to sagging under their weight, and form a ...

Two galaxies were observed at 1.6 μm at an angular resolution as high as 50 mas using the AO system on the Keck II telescope. Radial profiles of both objects are consistent with those of local spiral ...

W. M. Keck Observatory’s laser guide star adaptive optics (LGS AO) system uses a laser to create an artificial star to measure for atmospheric distortions. This results in sharp, high-resolution ...
