Although the basic principle of radio direction finding is easy to understand (measure the phase difference between different ...
Researchers developed a model showing the ability of reconfigurable intelligent surfaces to redirect the propagation of radio waves, which could improve the signal. A method to analytically express ...
For the first time, astronomers have captured radio signals from a rare exploding star, exposing what happened in the years leading up to its death. The radio waves reveal that the star violently shed ...
The majority of astrophysical radio sources are found in turbulent and magnetised environments (e.g., the intergalactic medium, pulsar nebulae, stellar coronae, and planetary magnetospheres). As the ...

Here’s how you can hack together a radio transmitter and receiver out of stuff you have at home—and explore the weirdness of wireless. The “Golden Age of Radio” supposedly ended in the ’50s, with the ...
Supermassive black holes reside in some of the biggest galaxies in the universe. They tend to be billions of times more massive that our Sun, and not even light itself can escape a black hole once it ...
A closed door feels absolute. Light stays in one room, darkness settles in the next, and the boundary seems obvious enough to stop thinking about. Yet the same wall that blocks the glow from your ...
A group of researchers in Antarctica have found strange radio waves coming from below the ice. According to the results published in the Physical Review Letters, the mysterious radio waves were ...
