Mysterious radio signal potentially from a distant 'super-Earth' puzzles scientists—is it alien?
Strange radio signals have been detected from the direction of K2-155 d, about 238 light-years away. Here's what it could mean.
Researchers are zeroing in on more deliberate “narrow-band” alien signals, well outside the radio frequencies SETI has focused on for decades. Reading time 3 minutes For over half a century, the ...

What steps can be taken to identify why we haven’t received radio signals from an extraterrestrial intelligence, also called technosignatures? This is what a recent study published in The ...
The search for extraterrestrial intelligence (SETI) has yet to detect alien technosignatures like radio waves, but the cosmos is vast, and there are plenty of places left to look. New research ...
On August 15, 1977, the Big Ear Radio Telescope in Delaware, Ohio, received the most powerful signal it would ever detect during its decades of observations. The signal lasted just 72 seconds, but ...
"Natural astrophysical processes rarely generate extremely narrow spectral features while engineered transmitters often do," writes a team of astronomers including first author Zi ...
