Stellar Space Weather Distorts Interstellar Signals, Shaping SETI Searches

To the point

Scientists at the SETI Institute say space weather from stars can distort radio signals, so some interstellar messages may be weakened or shifted and missed; by analyzing historical spacecraft transmissions at different distances from the Sun, they found noticeable distortion up to about 6.26 million kilometers, stronger when closer to the Sun, implying that searches for extraterrestrial signals should model stellar activity to better match arriving signals rather than just those sent.

The SETI Institute May Have Missed an Important Call from Aliens: Its All the Stars Fault

Scientists from the SETI Institute, who are engaged in the search for radio signals from extraterrestrial intelligent life, believe that some such messages may simply be ignored. Therefore, if extraterrestrial civilizations have tried to contact us,
