Represents the number of life-bearing planets in the galaxy. represents the total number of planets on which intelligent beings have evolved and developed a communicating civilization at some time in the galaxy's history. represents the number of planets in the galaxy that are in principle capable of having surface liquid water and life. essentially represents the probability that life eventually arises on a habitable planet. essentially represents the probability that on a planet with life, some organisms will eventually evolve to the point where they can build radio telescopes. is a factor that depends on how long civilizations that reach our level of technology are able to survive. represents the number of civilizations in our galaxy that we could in principle communicate with today.
