Alien messages may have reached Earth without us realizing it

A groundbreaking study by SETI suggests that alien signals might be reaching Earth but are getting lost in translation due to interference from their own stars. These M-dwarf stars, the most common in the Milky Way, can scatter narrow radio transmissions across a broad spectrum of frequencies, making it difficult for traditional detection methods to pick them up. This finding is significant as it reshapes our understanding of how to search for extraterrestrial intelligence, emphasizing the need to account for the unique astrophysical environments of potential alien civilizations.
