Space Weather Could Scatter Narrowband Signals from Intelligent Extraterrestrial Life, Reframing SETI Searches

To the point

Space weather from stars can blur and scatter ultra-narrow alien radio signals, particularly around planets orbiting small red dwarfs, so searches should focus on what actually arrives at Earth rather than what was transmitted, says Grayce C. Brown, while SETI broadens beyond the Milky Way to targets like TRAPPIST-1 and public interest grows after Obama and Trump commented on unidentified phenomena.
