Researchers have developed a new way to use femtosecond laser pulses to fabricate the high-precision ultrathin mirrors required for high-performance X-ray telescopes. The technique could help improve ...

system at the W. M. Keck Observatory is exceeding performance expectations and is poised to revolutionize many fields of astronomy. The new guide star system, the only one of its kind on a very large ...

The light from this space laser traveled a whopping 36 thousand billion billion miles (58 thousand billion billion kilometers) to reach our planet. An international team of astronomers, led by Marcin ...

Radio telescopes let you study the universe by collecting faint radio waves from distant objects. To see extremely small targets, such as the regions around supermassive black holes, those telescopes ...

We’ve showed you the Paranal Observatory’s laser-guided telescopes before, but never in gorgeous HD motion, replete with clear stars and deftly swiveling machinery. This is definitely one you’re going ...

It’s been quite a year for laser communications in space. In October and November, NASA launched two pioneering demonstrations to test high-bandwidth optical communication links, and these tech demos ...

WASHINGTON, Feb. 5 – Future telescopes, with mirrors half the size of a football field, will need special components to deal with the light they collect. Astronomers are turning to photonic devices ...

Astronomers have discovered the brightest and most distant "megamaser" to date. The cosmic energy beam is shooting toward ...

Researchers in Germany say that they have developed a lightweight and robust telescope for satellite-based laser links that is suitable for series production. Tesat is also working on a European Space ...
