Will artificial intelligence help us find evidence of UFOs?

"Are we alone in the universe?" is one of humanity's biggest questions. But now, some of the world's top scientists and tech companies are setting out to answer an even bigger question: "Are we being visited?" This used to be seen as a silly topic for debate, confined to conspiratorial subreddits filled with stories of reptilian alien overlords covertly living among us. But things are starting to change. Last year, not only did US president Biden approve a new US government office to study the nature of unidentified flying objects, but a distinguished academic, Professor Avi Loeb -- the longest serving chair of Harvard's Department of Astronomy -- launched The Galileo Project, a search for UFOs.
