A group of scientists from the SETI Institute, Seti Research Center in Berkeley, and the International Center for Radio Astronomical Research have achieved a significant milestone in the search for extraterrestrial civilizations. In a groundbreaking development, the researchers utilized low-frequency radio waves to detect signals of alien technologies beyond our galaxy.
Utilizing the MURCHISON WIDEFIELD Array (MWA) telescope with a wide field of view, the scientists were able to observe approximately 2800 galaxies simultaneously. The choice of 100 MHz radio waves was deliberate, as these waves have the capability to traverse vast cosmic distances and penetrate planetary atmospheres, making them an ideal medium for potential interstellar communication.
The focus of the study was on detecting signs of technologically advanced civilizations, also known as technologists. This new method opens up the possibility of identifying civilizations that may be more technologically advanced than our own. Advanced technologies capable of transmitting signals across galaxies would require harnessing the energy of stars, perhaps even multiple stars.
Stephen Tingye from Kertin University praised the innovative nature of the study and highlighted its implications for future observations with more powerful telescopes. He emphasized the significance of the MWA in advancing the exploration of the universe for both intelligent civilizations and technological advancements, while also advancing our understanding of astrophysics related to stars and galaxies.
