When it comes to telescope mirrors, larger is generally better. The larger your main mirror, the more light you can capture and the more faint and distant objects you can see. The problem is that ...

Someday, astronauts on the moon may pour liquid onto a disc-shaped mesh to make a huge mirror for a powerful telescope, according to a technical article just made public. The liquid would include a ...

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 ...

A team of astronomers from The University of Texas at Austin are bringing a truly moonshot concept back from the grave: a liquid-mirror telescope 100 meters in diameter, built on the surface of the ...

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 ...

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 ...
