\textbf{A series of amazing discoveries in the field of astrophysics occured in the last few months. We now know that planetary systems around stars other than the Sun are the norm, not the exception. The implications for one of the most fascinating questions we can ask, "Are we alone in the Universe", are enormous. We review the Drake equation in light of these recent discoveries. The absence of a clear detection of communicative extraterrestrial civilizations tells us that there should be it is likely  an important transition in the characteristic of the human civilization occuring will occur  in a timescale shorter than about 1000\...2000 years.} %The Drake equation can be used to estimate the likelihood of getting in touch with an extraterrestrial civilization.}
