Stellar Activity May Obscure Ultra-Narrow Radio Signals, Prompting SETI to Refine Search Strategies Around Red Dwarfs

To the point

SETI researchers say that stellar activity creates space weather that blurs ultra-narrow radio signals used to search for alien life, which could hide existing signals from current detectors, and they suggest broadening search methods by using higher frequencies and focusing on active red dwarf stars.

Stellar activity might be masking alien signals, says new study

NASA-funded research suggests that space weather phenomena could be distorting potential extraterrestrial signals, making them difficult to detect.
