A recent SETI Institute study suggests that space weather could blur and weaken extraterrestrial radio signals long before they reach us.

Radio silence has long puzzled those searching for extraterrestrial intelligence, but the answer might lie much closer to the ...

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

One of the longest-standing techniques in humanity’s search for life beyond Earth may be causing scientists to miss alien ...

The researchers who scan the skies for radio signals from extraterrestrials are now rethinking their approach.

A study by alien searchers at the SETI Institute (Search for Extraterrestrial Intelligence) could explain why humanity has not yet received any alien messages.

Researchers may have finally traced 1977’s famous extraterrestrial anomaly back toward massive, naturally occurring hydrogen emission flares.

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.

Turbulent plasma near distant stars could blur ultra-narrow signals before they leave their home star systems - making them difficult to detect.

Astronomers have been scanning the skies for alien radio signals for decades, but so far they’ve heard nary a peep (with one possible exception). But according to a recent study, that could be because ...

What steps can be taken to identify why we haven’t received radio signals from an extraterrestrial intelligence, also called technosignatures? This i | Space ...

Scientists believe turbulent “space weather” around distant stars could be scrambling potential alien signals before they ...
