Imagine a space telescope with a mirror stretching 50 meters across! That's larger than the width of a U.K. soccer field and ...

On May 20, 1990, the Hubble Space Telescope sent its first image to Earth. This photo turned out to be 50% sharper than ...

The world's most powerful telescopes, including the James Webb Space Telescope and FAST, are revolutionizing our ...

Its two telescopes, the 11.5-foot (3.5 meters) New Technology Telescope (NTT) and the 11.8-foot (3.6 m) telescope both use ultraprecise mirrors to bounce images back from space for analysis.

A unique new material that shrinks when it is heated and expands when it is cooled could help enable the ultra-stable space ...

Both cameras are far more sensitive than the standard cameras used on Earth. NIRCam and MIRI can detect the tiniest amounts ...

The game-changing Vera C. Rubin Observatory will collect more astronomical data in its first year than all other telescopes ...

L3Harris in Rochester played a pivotal role in building the Vera C. Rubin Observatory’s massive secondary mirror.

It didn’t work very well then, either. A good telescope mirror is accurate to at least 1/8 wavelength of sodium light, or 70-odd nanometers. Vibrations alone ruin the image. Report comment.

The Atmospheric Remote-sensing Infrared Exoplanet Large-survey (Ariel) telescope is to launch in 2029 and spend years ...

Because it shrinks when other materials expand, Allvar Alloy 30 can be used to strategically compensate for the expansion and ...

The Vera C Rubin observatory, home to the world's most powerful digital camera, promises to transform our understanding of ...
