Space Weather May Blur Ultra-Narrow Signals, Reframing SETI Searches — and a Separate US Declassification Push on Extraterrestrial Life

To the point

SETI Institute researchers backed by NASA say space weather can scramble ultra-narrow radio signals from distant civilizations by spreading energy across frequencies and weakening peaks, so Grayce C Brown and colleagues argue we need higher-frequency searches and pipelines tuned to what actually arrives on Earth, with Vishal Gajjar noting the star environment could make signals invisible to current equipment, and Donald Trump ordering all US agencies to declassify extraterrestrial documents after Barack Obama’s remarks, linking science with public-interest debates about aliens and government disclosures.
