Radio telescopes are one of the dark arts of science. Not only do you have to deal with RF wizardry, the photons you’re detecting are so far out of the normal human experience that you really don’t ...

KAIST researchers tested optical frequency comb lasers as reference signals for radio astronomy, aiming to synchronize radio telescopes with light-based timing in VLBI observations.

The Event Horizon Telescope (EHT) collaboration, with the participation of the Atacama Large Millimeter/sub-millimeter Array (ALMA), has for the first time received radio waves at 0.87 millimeters.

Radio interferometric imaging represents a pivotal advance in astronomical observation by combining signals from distributed radio telescopes to synthesise high-resolution images of celestial objects.

We now have direct images of two supermassive black holes: M87* and Sag A*. The fact that we can capture such images is ...

After decades of discussion, the far side of the moon --- the most radio quiet spot in the inner solar system --- is finally being taken seriously for a kilometers-wide, low- frequency radio array.

Launching aboard the European Space Agency's (ESA) Ariane 6 rocket on Tuesday, NASA's CubeSat Radio Interferometry Experiment (CURIE), will use two small cube satellites—which together measure no ...

A radio interferometer array operating at 20 GHz would be developed at Indian Institute of Technology, Indore (IIT-I) soon. The work on developing state-of-the-art interferometer, which is perhaps the ...

Before everyone knew about the giant black hole lurking in the center of our Milky Way galaxy, was just an exceptionally bright source of radio emission. But since the discovery of Sagittarius A* ...

When Ken Kellermann ’59 was a sophomore, he and the other physics majors had to take a class in optics. “I thought it was the most boring thing,” he recalls. “It was all 19th-century technology—shine ...
