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

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

A group of Chinese scientists is diving deep into the cosmos in search of alien radio signals from the TRAPPIST-1 star system, which might house planets that could support life. This is no small feat, ...

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

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 ...

SETI Institute researchers suggest solar winds may have obscured alien signals by widening their frequency bands, potentially causing us to miss evidence of extraterrestrial life. This discovery, ...

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

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.

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 ...

For decades, humanity has scoured the cosmos for any signs that we aren't alone in the universe. NASA spacecraft like the twin Voyager probes – launched in the 1970s bearing the iconic Golden Record – ...
