Astrophysical Journal Study Finds Space Weather May Distort Alien Radio Signals, Complicating Narrowband Searches

To the point

Grayce C. Brown and colleagues warn that space weather from other stars can distort ultra-narrow alien radio signals, scattering them across more frequencies and potentially causing missed detections, especially for planets around small M-dwarf stars, so SETI may need to adjust search strategies for both nearby and distant targets like TRAPPIST-1.

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