Background

"In early November, 1961, a group of scientists and engineers met at the Green Bank Observatory to discuss the possibility of using the techniques of radio astronomy to detect evidence of intelligent life outside our Solar System."[2] The Drake Equation, a tool used to estimate the number of communicating civilizations in the galaxy, was first discussed here. At the same time, the first SETI search, Project Ozma, was conducted at the National Radio Astronomy Observatory.[1]
