For decades, humans have sent probes into space to explore distant planets, and to go in search of evidence of things like life on other worlds. If humans engage in such activities, why wouldn't aliens do the same? Is it possible that Earth has ever been surveilled by extraterrestrial technologies, and that searches for non-terrestrial artifacts could reveal their presence close to Earth?  Beatriz Villarroel is a postdoctoral researcher holding the position of Nordic Fellow with Stockholm University, Sweden. Among other positions she holds, she is Principal Investigator of the "Vanishing & Appearing Sources during a Century of Observations" project, otherwise known as the VASCO Network. This week, she joins us to discuss the scientific search for non-terrestrial artifacts on The Micah Hanks Program.  The story doesn't end here... become an X Subscriber and get access to even more weekly content and monthly specials.
