Mankind has been passionate about the search for extraterrestrial civilizations for a long time. But now, in addition to ufologists discussing this topic, scientists have joined the case. British astrophysicists have calculated how many intelligent civilizations can exist in our Milky Way galaxy. In their calculations, scientists were guided by the latest astronomical data and took into account many parameters. Under intelligent civilizations, specialists understood technologically advanced societies - for example, having mastered radio communications, thanks to which communication with earthlings is possible.
The scatter of numbers turned out to be large: from 4 to 211. But the most probable researchers consider the number 36 - so many planets where life is possible may well exist in the Galaxy.
