Several scientific institutions and initiatives, including the SETI Institute, the Berkeley SETI Research Center and the International Center for Radio Astronomy Observations (ICRAR), have launched a new project to search for traces of technologically advanced civilizations in other galaxies.< /p>
The project is implemented on the basis of the Australian observatory Murchison Widefield Array, which houses a powerful radio system with 4096 antennas. The design of the antennas is designed in such a way to search for radio signals over long distances. Due to this, such a radio telescope is able to keep 2,800 galaxies in the field of view at once.
The outstanding part of the project is that other similar initiatives are aimed at searching for radio signals within our galaxy – Milky Way. For comparison: the stars in the Milky Way are 4-100,000 light-years away from the observer, and the nearby galaxies are at a distance of 2 million to 30 million light-years.
True, according to scientists' estimates, to record a radio signal from Earth, alien civilizations must be at a level of development many times higher than ours.
As notes Gizmodo, in the past this system was used to search for technosignatures, but no traces of extraterrestrial civilizations have been found yet.
