Space Weather Could Scatter and Weaken Extraterrestrial Signals, Shaping SETI's Search Strategy

To the point

SETI researchers, including Grayce C. Brown, say space weather from other stars can blur ultra-narrow signals from aliens and make traditional narrowband searches miss them, especially for planets around dim M-dwarf stars, so they urge focusing on signals that actually reach Earth and using adaptive, diverse search methods, such as extragalactic scans with the Murchison Widefield Array and work at TRAPPIST-1.
