Alien messages may have reached Earth without us realizing it

Researchers at the SETI Institute have discovered that stellar activity, such as plasma density fluctuations, may distort narrow-band radio signals from extraterrestrial civilizations. This interference could explain why current search methods have failed to detect alien technosignatures.
Why it matters
This finding challenges the fundamental assumptions of the search for extraterrestrial intelligence and suggests that detection strategies need to be updated to account for stellar environmental noise.
A new study from the SETI Institute suggests that the search for extraterrestrial intelligence may be facing an unexpected challenge. The same stellar activity that shapes conditions around distant planets could also make alien radio signals much harder to detect.
