Researchers have revealed a groundbreaking study conducted with the Murchison Widefield Array (MWA) located in Western Australia. This research marks the first attempt to search for evidence of extraterrestrial technology in galaxies outside our own, concentrating on low radio frequencies (100 MHz). This novel method examines distant galaxies, making it one of the most in-depth investigations for super civilizations—those that possess more advanced technology than we do.
The SETI Institute, Berkeley SETI Research Center, and the International Centre for Radio Astronomy Research have introduced a pioneering study with the Murchison Widefield Array (MWA) in Western Australia. Dr. Chenoa Tremblay from the SETI Institute and Prof. Steven Tingay from Curtin University lead this project, which is the first to look for signs of extraterrestrial technology in galaxies beyond our Milky Way, emphasizing low radio frequencies (100 MHz). This research takes advantage of the MWA’s extensive field of view (FOV), enabling the team to observe around 2,800 galaxies in a single observation, with confirmed distances to 1,300 of these galaxies.
Traditionally, the search for extraterrestrial intelligence (SETI) has been limited to signals within our galaxy. This innovative project expands the search to encompass distant galaxies. This approach is among the most thorough investigations for super civilizations—those that are significantly more advanced than humanity. To transmit signals from another galaxy, a civilization would require technology powerful enough to harness the energy of their sun or multiple stars.
“This research signifies a major advancement in our quest to identify signals from advanced extraterrestrial civilizations,” stated Tremblay. “The MWA’s extensive field of view and capability to explore low-frequency ranges make it an exceptional instrument for this type of research, and the parameters we have established will inform upcoming studies.”
Although this initial study did not uncover any technosignatures (indicators of alien technology), it offers valuable insights that will assist in refining future explorations. It underscores the necessity of investigating various radio frequencies and utilizing the unique features of telescopes like the MWA.
“The MWA continues to uncover fresh avenues for exploring the Universe for intelligent life and technosignatures, while simultaneously utilizing the same data to investigate the astrophysics of stars and galaxies. This research is innovative and unique, yet it lays the groundwork for future observations with even more advanced telescopes,” noted Tingay, who serves as the Director of the MWA.
This study underscores the significance of international cooperation and the application of advanced technology to broaden our comprehension of the Universe. The SETI Institute is dedicated to seeking evidence of intelligent life beyond Earth and enhancing our understanding of the cosmos.
