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 ...

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 ...

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 ...

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 ...

Lightning rods protect buildings by providing a low-resistance path for charges to flow between the clouds and the ground. But they only work if lightning finds that path first. The actual strike is ...

Dear Buyer's Guide Update Member, This edition of the DrBicuspid Buyer's Guide Update examines two of the most cutting-edge technologies in dentistry today: CAD/CAM systems and lasers. CAD/CAM systems ...

A group of scientists say they successfully steered bolts of lightning using laser technology during a storm in Switzerland, demonstrating a potential new method to protect infrastructure from ...

Many conventional spectrometric techniques have been effectively used in the detection of solids, liquids, and gases. However, newer laser spectroscopy techniques have emerged as the tools of choice ...

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 ...
