The new adaptive optics facility being built at the Very Large Telescope (VLT) in Chile passed a key milestone in the past few weeks, achieving "first light" with one of its four new laser guide star ...
University of California, Berkeley, astronomers have taken advantage of a recently mounted laser guide star system at UC’s Lick Observatory to obtain sharp, twinkle-free images of the faint dusty ...
Ground-based telescopes have long contended with atmospheric turbulence that diminishes image clarity, and the advent of adaptive optics combined with laser guide stars has been transformative in ...
Looking like a scene out of "Star Wars," this image shows the ESO's Very Large Telescope Interferometer (VLTI) beaming four ...
Following five years of development work, a new solid-state laser designed for guide star systems in giant telescopes is ready for deployment. Last week, the European Southern Observatory (ESO) said ...
WASHINGTON, D. C. — A new sodium laser is giving 50 times more sky coverage to the atmospheric-correcting technology known as adaptive optics on the Keck II telescope at Mauna Kea, Hawaii. The laser ...
A laser pointed at a stormy sky can divert the paths of potentially dangerous lightning strikes, a new study shows. Using a car-size prototype assembled atop a Swiss peak, an international group of ...
