(FOX NEWS) -- If extraterrestrial civilizations exist, we may not have to go too far to find them.

“The classic method for estimating the number of intelligent civilizations relies on making guesses of values relating to life, whereby opinions about such matters vary quite substantially," the study's lead author, Tom Westby, said in a statement. "Our new study simplifies these assumptions using new data, giving us a solid estimate of the number of civilizations in our Galaxy."
