We may be missing alien radio signals because they have become smeared beyond the narrowband detectors that SETI utilizes, a ...

Earthlings, brace yourselves: the galaxy may be emptier than your last Tinder date. According to a new study, any alien ...

E.T. could be phoning home — but we’re not hearing the call. A new study published in The Astrophysical Journal argues that “space weather” could be distorting incoming transmissions from ...

Institute has found that we may have missed transmissions from intelligent alien life for a very benign reason. SETI’s searches are focused only on very narrow signals, so the organization typically ...

The Search for Extraterrestrial Intelligence (SETI) focuses on finding technosignatures—potential signs of alien technology. If we look carefully, we might have a chance at detecting their ...

For over six decades, the Search for Extraterrestrial Intelligence (SETI) has been tirelessly scanning the cosmos for signs ...

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

What new methods can be used to detect alien technosignatures? This is what a recent study published in The Astrophysical Journal Letters hopes to address as a team of researchers from Pennsylvania ...

The Deep Space Network (DSN) is just the sort of tool aliens could one-day detect, transmitting from Earth. Credit: NASA/JPL What if the first signal ever detected from an alien lifeform wasn't a ...

For decades, the search for alien intelligence has revolved around the question: if someone out there is listening, how could they hear us? A new study combining data from Penn State and NASA’s Jet ...
