“The universe is not as quiet as we were told.” The line belongs to a dramatic retelling of a disputed signal claim, but it captures a sober scientific problem: the first technosignature humanity ...

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

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

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

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

For decades, humanity has been looking for answers to unravel the mystery surrounding aliens’ existence, but they have failed ...
