For centuries, scientists have worried about the presence of extraterrestrial civilizations in space.
To this end, the SETI project, which dates back to 1959, was set up. However, no reliable signs of other life forms have been found. A new study in the same series was unsuccessful.
It is reported that the latest study to search for traces of extraterrestrial civilizations in space was the fourth in a row. Scientists are trying to identify extraterrestrial signals at the center of the Milky Way by sending out low frequency radio waves. In the latest work, scientists sent a signal with a frequency of 150 MHz.
All work was carried out using the Murchison Widefield Array located in Australia. In the latest study, scientists observed over 140 previously discovered Earth-like exoplanets for two consecutive nights.
All are located in the heart of the galaxy. In total, the study lasted more than seven hours, but did not bear fruit.
However, scientists do not despair and will continue the search for extraterrestrial civilizations. According to the person in charge of the study, they will gradually modify the frequencies of the signal with a certain periodicity.
