An alien radio signal from K2-155 d? Are there any alien civilizations out there? For several decades, scientists have been searching for evidence that they exist. That effort is collectively known as ...
Radio silence has long puzzled those searching for extraterrestrial intelligence, but the answer might lie much closer to the source of potential signals than previously thought. Conditions around ...

Radio signals seen directly from an exoplanet for the first time—here's what astronomers found
The radio signals are not an indication of aliens trying to communicate with us. Instead, they are related to something we ...
The discovery could help astronomers determine whether an outer world is suitable for life.
If advanced aliens lived on a planet within a few hundred to a thousand light years away from Earth, then vast numbers of their signals must already have crossed Earth without being noticed, a new ...
Add Yahoo as a preferred source to see more of our stories on Google. An illustration of an exoplanet in an alien star system. New research suggests that radio emissions from intelligent aliens may be ...
When/if alien life ever cruises toward Earth in big spaceships, we’re probably not just going to see it; we’re going to hear it via narrow radio signals. If an extraterrestrial civilization wanted to ...
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 ...
"Natural astrophysical processes rarely generate extremely narrow spectral features while engineered transmitters often do," writes a team of astronomers including first author Zi ...
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 ...
