The Drake Equation N = R * · f p · n e · f l · f i · f c · L Where, N = The number of civilizations in The Milky Way Galaxy whose radio emissions are detectable. R* = The rate of formation of stars suitable for the development of intelligent life. f p = The fraction of those stars with planetary systems. n e = The number of planets, per solar system, with an environment suitable for life. fl = The fraction of suitable planets on which life actually appears. f i = The fraction of life bearing planets on which intelligent life emerges. f c = The fraction of civilizations that develop a technology that releases detectable signs of their existence into space. L = The length of time such civilizations release detectable signals into space.
