New research provides a physics based solution for why we aren't hearing potential messages from alien civilizations.
Solar winds and coronal mass ejections may scatter narrow signals, making them harder for Earth-based telescopes to detect. The SETI Institute uses radio telescopes to search for signs of intelligent ...
The researchers who scan the skies for radio signals from extraterrestrials are now rethinking their approach.
SETI has spent decades listening for a sharp, well-defined radio signal that could indicate it was sent by distant ...
We may be missing alien radio signals because they have become smeared beyond the narrowband detectors that SETI utilizes, a ...
Stellar plasma can smear alien radio signals before they escape their star system, making them harder for astronomers to ...
E.T. could be phoning home — but we’re not hearing the call. A new study published in The Astrophysical Journal argues that ...
