There could be as many as 42,777 intelligent alien civilizations in our galaxy that could make contact within the next 2,000 years, scientific research shows, The Daily Caller reported. The research was published in The Astrophysical Journal, and the findings have an error rate of plus or minus a few hundred. The authors based those results on an optimistic estimate that only 0.1% of alien civilizations could advance to the degree that interstellar communication within the Milky Way galaxy would be possible, The Daily Caller noted. Signal heard at the Big Ear radio telescope in Ohio in 1977 is the only signal ever potentially received from alien life, according to Forbes. "If so, the number of [communicating extraterrestrial intelligent civilizations] CETIs would become even lower, and the opportunities for communication between CETIs would become extremely small."
