The Drake equation is as follows:
- N: The number of civilizations with which we might be able to communicate.
- R*: The average rate of star formation in our galaxy.
- fp: The fraction of stars which, after formation, have 1 or more planets.
- ne: The average number of planets that can potentially develop life, per star which has 1 or more planets.
- fℓ: The fraction of planets that actually do develop life.
- fi: The fraction of life-developing planets that actually do develop intelligent life.
- fc: 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.
