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

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

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.

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 ...

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 ...

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

Advanced aliens could be chatting with each other using light flashes in plain sight, similar to how fireflies communicate, according to a new study that could lead to new approaches in finding ...

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

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

Scientists hunting for extraterrestrial life believe alien civilisations may indeed be attempting to contact Earth, but ...

Green Bank Telescope rules out alien signals in interstellar comet 3I/ATLAS after rigorous scientific deep search.
