Astronomers Say Advanced Alien Civilizations Have Existed
Astronomers Adam Frank and Woodruff Sullivan, at the University of Rochester and the University of Washington respectively, published a paper in the May issue of the journal Astrobiology exploring what they call the “cosmic archaeological question”: “How often in the history of the Universe has evolution ever led to a technological species, whether short- or long-lived?”
Frank summed up their conclusion in an op-ed for the New York Times, published June 10: “While we do not know if any advanced extraterrestrial civilizations currently exist in our galaxy, we now have enough information to conclude that they almost certainly existed at some point in cosmic history.”
We now have enough information to conclude that they almost certainly existed at some point in cosmic history.

The astronomers came to this conclusion by reworking the famous Drake equation from a different perspective, also adding up-to-date information. The equation was originally formulated by astronomer Frank Drake in 1961 to calculate the odds of contact with alien life.
Drake studied radio astronomy at Harvard and held various posts in the field, including at NASA’s Jet Propulsion Laboratory. He included in his equation various factors, such as the rate of formation of stars suitable for the development of intelligent life and the number of planets in each solar system with an environment suitable for life.
