The published catalog of objects for the search of extraterrestrial life

Project Breakthrough Listen to search for signs of intelligent life in the Universe announced the release of a catalogue of Exotica, including a complete list of objects that can be linked to man-made signals. The results of the study in the form of a Preprint published on the website of the University of California at Berkeley.

The search for extraterrestrial intelligence has long been seen as a serious scientific problem. In the framework of the global program SETI (Search for Extraterrestrial Intelligence) entrepreneur Yuri Milner in 2016 launched a project Breakthrough Listen — initiative to search for signs of intelligent life in the Universe in thesignature — potentially man-made signals.

The company Listen greatly expanded search capabilities, has developed a search technology using giant radio telescopes deployed on three continents, which allowed us to cover an unprecedented range of frequencies with high resolution.

All that was found similar in space over the years, included in the innovation catalogue Exotica, which includes 700 different goals for the study — from comets to galaxies, from individual objects to large-scale celestial phenomena.

The fundamental principle of the approach Listen — breadth of the review, the variety of objects observed in the course of the program. According to the authors of the project, it will help astronomers to constrain the range of potential habitats for extraterrestrial intelligence, as well as to exclude the possibility that any phenomena that are typically considered natural, in fact will be artificial.

Directory Exotica contains four categories: 1) prototypes of celestial objects — planets, stars, galaxies and so on
