A new study published in The Astrophysical Journal by SETI Institute researchers finds that stellar space weather — including coronal mass ejections and plasma turbulence — could broaden narrowband radio signals from extraterrestrial civilizations, causing them to slip below detection thresholds. The research reveals that 70% of stars could distort signals by more than 1 Hz, with M-dwarf stars (75% of the Milky Way) posing the greatest challenge, and proposes recalibrating SETI search strategies to account for these previously overlooked cosmic interference effects.
