Signals from extraterrestrial life may have gone undetected because they are being distorted by the environments of distant star systems.

\nAstronomer Vishal Gajjar from the SETI Institute led a new study examining how so-called technosignatures \u2013 radio signals potentially sent by intelligent alien life \u2013 could be altered before they reach Earth.

\nFor decades, scientists involved in the Search for Extraterrestrial Intelligence have focused on detecting extremely narrowband radio signals, which are unlikely to occur naturally.

\nHowever, the research suggests activity from nearby stars may broaden these signals, spreading them across multiple frequencies and making them harder to detect with existing methods.

\nThe findings were published in The Astrophysical Journal.

\nSpeaking about the study, Vishal said: \u201cSETI searches are often optimized for extremely narrow signals. \u201cIf a signal gets broadened by its own star\u2019s environment, it can slip below our detection thresholds, even if it\u2019s there, potentially helping explain some of the radio silence we\u2019ve seen in technosignature searches.\u201d

\nA research team analysed how radio signals behave by studying transmissions from spacecraft within our own solar system.

\nThis allowed them to model how signals might be affected by stellar conditions closer to their source, rather than solely during their journey across interstellar space \u2013 an area that has traditionally received more attention from astronomers.

\nGrayce C Brown, a research assistant and co-author of the study, said: \u201cBy quantifying how stellar activity can reshape narrowband signals, we can design searches that are better matched to what actually arrives at Earth, not just what might be transmitted.\u201d

\nThe findings indicate that solar activity, often referred to as space weather, could play a significant role in masking potential evidence of extraterrestrial communication.

\nWhile scientists have long accounted for distortions that occur over vast interstellar distances, the study highlights the importance of considering interference within alien star systems themselves.

\nResearchers developed a framework to better understand how signals become distorted, with the aim of improving future search strategies.

\nBy refining detection methods to account for these effects, scientists hope to increase the chances of identifying technosignatures that may previously have gone unnoticed.

\nThe study, titled Exo\u2013IPM Scattering as a Hidden Gatekeeper of Narrowband Technosignatures, forms part of ongoing efforts to refine how scientists search for evidence of life beyond Earth, as interest in extraterrestrial detection continues to grow.
