Where is the best place to meet kind and peaceful aliens? How do we communicate with intelligent interstellar life forms, socialise with Martians, and avoid unwanted close encounters of the third kind? Here is a map of the portals that open up between the worlds, a geography of strange events that covers the entire earth, demonstrating how widespread the phenomenon is. Learn about locations of sightings, hidden bases, secret embassies, and long-lost traces of thousand-year-old passages. From the UFO port of Ars to the underground center of Area 51, from the crash at Roswell to setting up the SETI program, this atlas lists, for the first time, the meeting points between earthlings and EBE, these mysterious extra-terrestrial biological entities.
