Drake Equation

Calculate the number of advanced civilizations in our galaxy.

N = R* · f_p · n_e · f_l · f_i · f_c · L

Star formation rate (R*): Fraction of stars with planetary systems (f_p): Number of planets per star system that can support life (n_e): Fraction of those planets where life develops (f_l): Fraction of planets with life where intelligent life evolves (f_i): Fraction of civilizations that develop detectable technology (f_c): Duration of the detectable phase of the civilization (L):

Result: 0 civilizations

This graph represents the estimated number of technologically advanced extraterrestrial civilizations in the Milky Way galaxy capable of interstellar communication.

The chart illustrates how this number changes based on the star formation rate (R) — one of the key parameters in the Drake Equation.

These civilizations are hypothesized to have developed detectable signals, such as radio technology, which could be observed by our astronomical instruments. The estimate incorporates other factors like planetary habitability, the emergence of intelligent life, and the longevity of such civilizations.
