Stellar plasma can smear alien radio signals before they escape their star system, making them harder for astronomers to detect.

New SETI research suggests space weather like solar winds could be interfering with alien radio signals, making them harder ...

Solar storms around distant stars may be erasing alien radio signals before we ever hear them In A Nutshell Stellar winds and ...

For four decades, many SETI experiments have focused on finding sharp spikes in frequency but the new study says signals may not stay narrow as they travel away from their home system.

SETI researchers may have missed alien signals due to a cosmic phenomenon that distorts narrowband radio waves, new research says.

What does it take to detect a radio signal sent by extraterrestrial life to Earth? Two decades of work involving radio telescopes stationed on opposite sides of the world, a supercomputer in Germany, ...

Very-long baseline interferometry (VLBI) is a technique in radio astronomy whereby multiple radio telescopes cooperate to bundle their received data and in effect create a much larger singular radio ...

For the first time, a team of US researchers has used sensors containing highly excited Rydberg atoms to detect signals from an ordinary handheld radio. Through a careful approach to demodulating the ...
