Thanks to the Drake Equation we can estimate the number of civilizations in our galaxy, the Milky Way, with detectable radio emission. Try out your own numbers by adjusting each triangle using the +/- buttons, or check  predefined variables like today’s optimistic or skeptical scientific estimates, and then click calculate.

According to scientists, the Milky Way could contain between 1000 and 4000 million (1 to 4 billion) planets, with a minimum of 1,500 planets only 50 light years away from Earth, of which 50 million could be habitable.
