"There should be at least a few dozen active civilizations in our Galaxy under the assumption that it takes 5 billion years for intelligent life to form on other planets, as on Earth," Christopher Conselice, Professor of Astrophysics at the University of Nottingham and lead author of the study, said in [a statement](). "The idea is looking at evolution, but on a cosmic scale," he added. The researchers say the numbers suggest there are a number of technological civilizations in the Milky Way galaxy. "In the strong criteria, whereby a metal content equal to that of the Sun is needed (the Sun is relatively speaking quite metal rich), we calculate that there should be around 36 active civilizations in our Galaxy," Tom Westby, first author and assistant professor at the University of Nottingham, said in the statement. Previous estimations have been based on educated guesses and opinions — something that can cause numbers to "vary quite substantially," according to Westby. But the astronomers say their estimation takes the latest research into account. "Our new study simplifies these assumptions using new data, giving us a solid estimate of the number of civilizations in our Galaxy," Westby added. Hidden in the cool research is a major bummer: the average alien civilization would be 17,000 light-years away. It's also possible that all other intelligent civilizations already kicked the bucket a long time ago. But finding them could give us important clues about our own humanity as well. "If we find that intelligent life is common then this would reveal that our civilization could exist for much longer than a few hundred years, alternatively if we find that there are no active civilizations in our Galaxy it is a bad sign for our own long-term existence," Conselice said. "By searching for extraterrestrial intelligent life — even if we find nothing — we are discovering our own future and fate," he added. **READ MORE:** [Research sheds new light on intelligent life existing across the galaxy]() \[University of Nottingham\] **More on alien life:** *[Harvard Prof: Deep Space Signal May Be From Alien Civilization]()* ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
