$N = R \times f_p \times n_e \times f_l \times f_i \times f_c \times L$  It is a simple product of terms giving the number $N$ of civilizations in the Milky Way Galaxy with whom we could make contact. The terms in the equation are:  \begin{itemize}  \item %\item  $N$ is the number of civilizations in the Milky Way Galaxy with whom we could make contact. \item $R$ is the rate of star formation, which tells how many stars are born every year in our Galaxy.  \item $n_e$ is the average number of habitable planets in any planetary system  \end{itemize}
