Waiting for Contact - Lawrence Squeri - Bog

Imagine a network of extraterrestrials in radio contact with each other across the universe, superior beings who hail from advanced civilizations quadrillions of miles away, just waiting for Earth to tune in. This title tells the story of the Search for Extraterrestrial Intelligence movement, which emerged in 1959 as new technological developments allowed astronomers to begin using radio telescopes to listen for messages from space.
