Stellar Space Weather Could Distort Interstellar Radio Signals, Reframing SETI Searches
To the point
A new study says space weather around distant stars can distort and weaken radio signals from planets long before they reach Earth by spreading the signal across many frequencies with stellar winds and flares, which could explain the Great Silence and means SETI should consider how active stars reshape narrow-band signals, since red dwarfs like TRAPPIST-1 could be major culprits.
