“This work represents a significant advance in our efforts to detect signals from advanced extraterrestrial civilizations.”This is how Dr. Chenoa Tremblay of the SETI Institute expresses the beginning of the first search for signs of extraterrestrial technology in distant galaxies which is carried out from Australia.
The research is being conducted by the SETI Institute, the Berkeley SETI Research Center, and the International Center for Radio Astronomy Research and focuses on finding such signals using low radio frequencies (100 MHz) using a large structure.
The search for signs of terrestrial technology begins
The large structure used is that of Murchison Widefield Array (MWA), a 4,096-antenna radio observatory (that look like spiders) located west of Australia, which is responsible for the function of deep space radio observations. The study has used the large field of view of the MWA to scan 2,800 galaxies in a single observation.
As reported by SETI, previous searches mostly focused on sources of radio signals coming from our Milky Waybut this new approach goes further and looks at distant galaxies, making it one of the most detailed searches for supercivilizations more advanced than ours.
They claim that for an extraterrestrial civilization from another galaxy to send a signal, their civilization would need technology powerful enough to harness the energy of its sun or several stars of its galaxy. This structure was already used in 2020 to search for extraterrestrial signatures, but no trace was found.
As it has not been possible, in this first study, to find any type of technological signals or Signs that aliens are using their own technologybut information has been obtained for future searches. They emphasize the importance of continuing in Searching for intelligent civilizations with the MWA while using the same data to study the astrophysics of stars and galaxies.
