Space Weather Could Distort Technosignals, Shaping SETI's Galaxy-Spanning Searches and M-Dwarf Targets

To the point

Grayce C. Brown and colleagues at SETI say space weather from other stars could smear ultra-narrow technosignals so they arrive spread across many frequencies, making them harder to detect with traditional narrowband searches, especially on planets around small M-dwarf stars, and this idea helps steer broader searches that now scan thousands of galaxies and study targets like TRAPPIST-1 as NASA and private spaceflight progress continues and public interest in aliens remains high despite no confirmed contact.
