Today’s 8-meter class, optical telescope mirrors are such expensive glass behemoths that when actually moved to their mountaintop vistas, they frequently arrive with helicopter escorts. Local ...

India’s first liquid mirror telescope is up and running. It’s the first and largest liquid mercury telescope to be built at a high altitude, and if that isn’t impressive enough, it is also the first ...

At 8,040 feet above sea level (2,450 meters) in Uttarakhand, India, lies a prime site for astronomical observations — Devasthal, 31 (52 kilometers) miles east of the resort town Nainital. Surrounded ...

LAVAL, Quebec, Oct. 12 (UPI) -- Telescopes that collect cosmic light using giant mirrors made of liquid mercury are a promising technology may significantly lower the high cost of making scientific ...

A team of Canadian and American scientists has made a liquid mirror that could one day be used to build a large moon-based telescope. The research team, led by Ermanno Borra of the University Laval in ...

Put a puddle of mercury into a bowl, set it spinning and the liquid will spread out in a thin film across the surface. The result is a concave mirror with a surface so smooth that it rivals anything ...

Scientists in Canada are reporting progress toward a new type of "liquid mirror" -- mirrors made with highly reflective liquids -- whose shape can be changed to provide superior optical properties ...

Scientists have successfully coated a liquid surface with a thin layer of silver metal, creating a highly reflective mirror that could be used to create mammoth liquid-mirror telescopes on the moon.

Researchers in Canada have built the first deformable liquid mirror from a magnetic liquid or “ferrofluid”, which could someday be used to compensate for distortion in the images of telescopes and ...

Freelance writer Amanda C. Kooser covers gadgets and tech news with a twist for CNET. When not wallowing in weird gear and iPad apps for cats, she can be found tinkering with her 1956 DeSoto. NASA's ...

Using a patented coating technique, the team creates its liquid mirror by depositing a 150 nm thick metal liquid-like film (MELLF) on to a 5 mm-deep layer of water or oil in a Petri dish. Consisting ...
