SETI: Are we alone in the universe?

This week, Tech 24 takes a look at the search for extraterrestrial intelligence. Today, scientists believe that using artificial intelligence could be their best shot at helping intercept signs of alien intelligence. We speak to Andrew Siemion, the director of the Breakthrough Listen Project at the SETI Institute at UC Berkeley. He tells us how his team discovered 72 new fast radio bursts with AI. Plus, we look at apps that will help you identify celestial bodies in the sky.
