Stellar Turbulence May Blur Extraterrestrial Signals, Reframing SETI Approaches

To the point

New findings show that turbulent plasma around stars can broaden and weaken sharp radio signals from alien technology, so searches should test a range of signal widths and resolutions to recover hidden power and avoid missing signals that arrive as broader, fuzzier bands.
