More than 20,000 radio antennas will soon connect over the Internet to scan largely unexplored radio frequencies, hunting for the first stars and galaxies and potentially signals of extraterrestrial ...

Radio astronomy has long been unsung and underappreciated, largely because it's never been able to cough up the kind of jaw-dropping visual images that are routine with large optical telescopes. But ...

Sometimes you only need one of these big guys to come your way,” observed Julián Alvarado-Gómez of the Leibniz Institute for Astrophysics Potsdam. These comments evoke the significance of the recent ...

A team of astronomers and engineers at ASTRON, the Netherlands Institute for Radio Astronomy, has successfully detected correlated interferometric radio signals, called “fringes,” from the sky with ...

As China's contribution to the world's largest intergovernmental international radio telescope project Square Kilometer Array Observatory (SKAO), the first batch of the China-built middle-frequency ...

While these modeling results paint a potentially bleak picture, there is a very large degree of uncertainty in the space environments to which exoplanets are exposed. The biggest issue is the lack of ...

U.S. Naval Research Laboratory scientists from the Radio Astrophysics and Sensing Section of the Remote Sensing Division in conjunction with radio astronomers and engineers from the National Radio ...

The HFA is an acoustic "window" used in conjunction with the high frequency sail array. The primary purpose of an HFA window is to provide an acoustically transparent interface to seawater from the ...

Frequency diverse array (FDA) MIMO radar techniques represent a substantial evolution in radar system design, combining the benefits of frequency diversity with multiple-input multiple-output (MIMO) ...
