+== SETI Thinks It Might Have Missed a Few Alien Calls. Here’s Why ==
+The researchers who scan the skies for radio signals from extraterrestrials are now rethinking their approach.
+Matthew Phelan - March 9, 2026
+Scientists hunting for radio signals from any form of advanced extraterrestrial life that might be out there trying to contact us are now starting to wonder if something has been messing with their work.
+A new study published by researchers at the SETI Institute, short for the Search for Extraterrestrial Intelligence, has tested the possibility that “space weather” could render strong premeditated alien broadcasts into the kind of fainter radio signals that SETI typically ignores.
+“SETI searches are often optimized for extremely narrow signals,” according to Vishal Gajjar, an astronomer at the SETI Institute and lead author on the new work, published this past Thursday in the American Astronomical Society’s Astrophysical Journal.

+== SETI admits its search for alien life may be too narrowly focussed ==
+Solar winds near aliens’ homes – and ours – might be blowing away signs of alien technosignatures by broadening signals
+Simon Sharwood - Tue 10 Mar 2026 05:27 UTC
+The SETI Institute, the nonprofit that conducts a search for extraterrestrial intelligence by examining radio waves for artefacts that are unlikely to be the result of natural processes, thinks it may have been going about it the wrong way.
+As explained in a paper and post published last week, SETI points out that it has focussed its attention on narrowband signals and tries to compensate for interstellar events that might distort signals.
+The organization’s new research points out that solar winds or coronal mass ejections may distort signals within aliens’ star systems. SETI therefore hasn’t been looking for likely signals that We Are Not Alone, because it assumed that alien civilizations transmitted narrowband signals.
+“If a signal gets broadened by its own star’s environment, it can slip below our detection thresholds, even if it’s there, potentially helping explain some of the radio silence we’ve seen in technosignature searches,” said Dr. Vishal Gajjar, Astronomer at the SETI Institute and lead author of the paper.
+SETI’s researchers made that suggestion after studying data describing signals sent by human-made probes and finding signal distortion on many missions – the paper mentions Mariner IV, Pioneers 6, 10, and 11, Helios 1 and 2, Viking missions to Mars, Mars Express, Venus Express, and Rosetta missions.

+== Space Command chief throws cold water on the question of UAPs in space ==
+“I am not aware of anything that is extraterrestrial, other than comets and things like that.”

+DENVER—Last month, President Donald Trump took to social media with an announcement that he would direct the Pentagon and other federal agencies to “begin the process” of disclosing government files related to alien life and UAPs (unidentified anomalous phenomena). It was the latest chapter in a yearslong slow burn of sensational claims, congressional hearings, and yes, the military’s release in 2020 of intriguing videos that do, indeed, appear to show things that defy simple explanations.
+Subsequent reports from NASA and the Office of the Director of National Intelligence (DNI) did not find any link between the unexplained phenomena and aliens, but that didn’t stop enthusiasts from wanting to know more.
+“To date, in the peer-reviewed scientific literature, there is no conclusive evidence suggesting an extraterrestrial origin for UAP,” a NASA blue-ribbon panel wrote in a 2023 report. “The limited amount of high-quality reporting on unidentified aerial phenomena hampers our ability to draw firm conclusions about the nature or intent of UAP,” the DNI report stated in 2021.
+Government officials have said little about Trump’s most recent social media post on the matter. The president cited “tremendous interest” in the files, whatever they might contain. Perhaps the most famous UAP videos released by the Pentagon to date were captured by cameras on Navy fighter planes operating over the sea.
