Space Weather Could Blur Interstellar Signals, Reframing SETI Searches

To the point

Vishal Gajjar and Grace C Browyn of the SETI Institute warn that space weather can blur narrow alien radio signals by spreading their power across many frequencies, making them harder to detect, based on calibrations with spacecraft transmissions and applying the results to distant star systems, implying future searches should use higher frequencies and new strategies because some messages could be present but undetectable with current methods.
