The international SETI (Search for Extra Terrestrial Intelligence) programme recently involved the Sardinia Radio Telescope, equipped with a 64-metre diameter dish, to explore the central region of our galaxy in search of possible technological signals from alien civilisations.
The initial results, which will be published in the journal Acta Astronautica, were presented during the International Astronautical Congress in Milan. This initiative is the result of collaboration between the National Institute for Astrophysics and the Breakthrough Listen project, which has been using the large Sardinian antenna to analyse specific radio frequency bands since 2022.
The Italian radio telescope examined signals coming from the central region of the Milky Way, rich in stars and planetary systems, and from 72 stars identified as \u201csources of interest\u201d by NASA's TESS mission. \u201cIt is plausible that an extraterrestrial engineer could know and use radio technology, but we cannot predict the frequencies they might use,\u201d explained Lorenzo Manunza of the University of Cagliari, who led the study.
The research team also includes Monica Mulas, Luca Pizzuto and Alice Vendrame from the University of Cagliari, along with Andrea Melis and Maura Pilia from INAF and other American researchers. \u201cIt is essential to cover as many radio channels as possible using a variety of observational facilities,\u201d added Manunza. Although the research has not detected any messages attributable to alien civilisations, it remains of great value. \u201cThe Sardinia Radio Telescope,\u201d said Melis, \"is helping to reduce uncertainties about the power required for any extraterrestrial transmitters to reach us in the frequencies observed so far.\".<\/p>","protected":false},"excerpt":{"rendered":"
