Carl Sagan Explaining The Drake Equation


Professor Frank Drake offered an equation that assist in evaluating the number of noticeable extraterrestrial civilizations in the Milky Way galaxy. Carl Sagan puts it in perspective.

Essentially, Drake decided to outline a series of regulating factors, so that we could add the total number of recognizable stars, then scope way down to get to some approximation for how many might have civilizations that we could actually be able to contact.

The resulting Drake Equation is one of the most stimulating result of math I’ve ever seen. The Drake equation states that:

This artist's illustration of Supernova 1987A is based on real data and reveals the cold, inner  regions of the exploded star's remnants (in red) where tremendous  amounts of dust were detected and imaged by ALMA. This inner region is  contrasted with the outer shell (lacy white and blue circles), where the blast wave from the supernova is colliding with the envelope of gas ejected  from the star prior to its powerful detonation.
