A research by the Institute Seti funded by the Nasa: "The radio signals transmitted by the cosmos disturbed by the storms in space." If E.T. calls home and no one answers is the fault of the "maltempo..."
Astronomers suggest that space weather in other planetary systems may affect the detection of signals that could be emitted by an advanced alien civilization. The article, "Space weather in other planetary systems may hinder the detection of signals from alien civilizations," comes from the website Everything That Matters.
The Hidden Reason Alien Signals May Be Invisible
A new analysis has delivered one of the most disruptive findings in technosignature research in years. The study shows that a narrowband radio signal leaving an exoplanet does not travel through empty space. It must first pass through the turbulent environment surrounding its host star. That environment is violent, dense, and unpredictable. It reshapes a […] The post The Hidden Reason Alien Signals May Be Invisible appeared first on Above The No…
Researchers at the SETI Institute have just published a study that could explain why, after decades of listening, no extraterrestrial radio signals have always been received. The space weather around the stars would blur transmissions before they even left their original system. And 75% of the stars of the Milky Way would be affected. So, the space weather blurs the tracks The study, published in The Astrophysical Journal, starts from a rather s…

slashdot.orgNew SETI Study: Why We Might Have Been Missing Alien Signals
After decades of searching for extraterrestrial intelligence, the nonprofit SETI Foundation has an announcement. "A new study by researchers at the SETI Institute suggests stellar 'space weather' could make radio signals from extraterrestrial intelligence harder to detect." Stellar activity and plasma turbulence near a transmitting planet can broaden an otherwise ultra-narrow signal, spreading its power across more frequencies and making it more…
