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

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.

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

SETI researchers may have missed alien signals due to a cosmic phenomenon that distorts narrowband radio waves, new research says.
