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

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 ...

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.

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 ...

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 ...

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 ...

Researchers who listen for signs of non-human life say signals ‘can slip below detection thresholds, even if it’s there’ ...

Lee said SETI’s paper could answer the Fermi Paradox, the idea that if the universe is billions of years old, where are all ...

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 ...
