Scientists from the California Institute of Technology, NASA’s Jet Propulsion Laboratory and Santiago High School have identified the most likely habitat for a̳l̳i̳e̳n̳ c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s̳ in the Milky Way.

The researchers also took into account such a factor as the self-destruction of intelligent beings. This is reported in an article published on the arXiv.org preprint repository.
To assess the prevalence and age of a̳l̳i̳e̳n̳ c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s̳, experts used a galactic simulation model that takes into account the probability of abiogenesis (the origin of life from nonliving matter), the rate of evolutionary changes and the probability of the de̳a̳t̳h̳ of a civilization. It turned out that the last parameter most of all affects the number of intelligent c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s̳ and their age.

According to the simulation results, the largest number of possible a̳l̳i̳e̳n̳ c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s̳ inhabits the ring region located four thousand parsecs (one parsec equals 3.2 light years) from the center of the Milky Way. The distance from the center of the galaxy to the Sun is 8.5 thousand parsecs.

At the same time, more and more c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s̳ disappear over time, but the inner regions of the Milky Way remain the most densely populated. In addition, most intelligent life forms of the Milky Way are young, making them difficult to detect.
