AdminThe Search for Extraterrestrial Intelligence (SETI) recently surveyed over 1,300 galaxies, alien Searching for life using unexplored low-frequency radio waves. The search was reportedly conducted using the Murchison Widefield Array (MWA), a radio telescope located in the Australian outback. The effort targets the 80-300 MHz frequency band, which is relatively uncharted territory for SETI, which has traditionally focused on higher frequencies such as hydrogen emission lines at 1,420 MHz. Despite the search, no extraterrestrial signals were detected, but the discovery helped refine predictions about the possible power of alien transmitters.
Exploring unknown frequencies
of search The study was led by Chenoah Tremblay of the SETI Institute in California and MWA director Steven Tingay of Curtin University in Australia. Their work focused on a 30-degree field of view in the constellation Vela and looked at 2,880 galaxies.
Of these, the distances to 1,317 galaxies were known with high precision, allowing the researchers to place constraints on the power of their possible transmitters, indicating that the search may have detected signals with a transmission power of 7 x 10^22 watts at 100 MHz.
Significance of the findings
No signal was found, study The survey has provided valuable insights for future SETI research. The constraints set by the survey will guide further research, especially in the low-frequency region. Tremblay and Tingay point out that Earth itself has a strong source of low-frequency radio emissions, justifying continued exploration in this region, Live Science reports. ReportThe study highlights the importance of covering a wide range of frequencies to improve the chances of detecting extraterrestrial signals in the future.
As the search for extraterrestrial life continues, these discoveries highlight the challenges and complexities of combing the universe for signs of intelligent civilization.
