Solar Interference Undermines Narrowband SETI, Encouraging Broader-Spectrum Signal Searches

To the point

Solar winds can smear a 100 MHz signal down to about 100 Hz, so narrow-band searches may miss messages from intelligent civilizations; scientists Vishal Gajjar, Grace Brown, John Elliott, and Eric Atwell argue for broader spectra and smarter AI analysis, METI advocates active broadcasting, and viewing Earth as an exoplanet shows the shift from a bright 1960s beacon to a quieter signal, with odds still tiny but search methods expanding.
