Nasa has successfully sent a laser signal about 290 million miles, smashing previous records and potentially transforming our exploration of the solar system. The milestone was reached by Nasa’s Deep ...

The signal, deemed the most distant hydroxyl megamaser ever detected, was intercepted by the MeerKAT radio telescope in South Africa, which features 64 antennas. A hydroxyl megamaser is a giant ...

A German satellite transmitted a laser signal to a ground station mounted on a Jeep in a breakthrough test that could significantly alter space-to-Earth communication, speeding it up and avoiding data ...

The easiest way to knock a drone that poses a safety or security threat out of the sky is to hinder the wireless communications between the aircraft and those at its controls. But signal jammers that ...

Launching this summer, NASA’s Laser Communications Relay Demonstration (LCRD) will showcase the dynamic powers of laser communications technologies. With NASA’s ever-increasing human and robotic ...

A quantum trick based on interferometric measurements allows a team of researchers at LMU to detect even the smallest movements of a laser beam with extreme sensitivity. Researchers at Umeå University ...

Artificial-intelligence-generated content has driven explosive data traffic growth in data-center interconnects. Traditional direct detection solutions struggle with limited spectral efficiency and ...

Stable lasers play a significant role in precision optical systems where an electro-optic laser frequency stabilization system, such as the Pound-Drever-Hall technique, measures laser frequency and ...

A thin, stubbornly bright line showed up in data from the MeerKAT radio telescope that did not fit the usual rules of distance. The feature sat in a familiar part of the radio spectrum, but it was ...
