In 1908 the Tunguska explosion in Siberia knocked down an area of forest larger than London. Most scientists believe that a fragment of an asteroid or a comet caused the blast, but neither a crater nor unmistakable remnants of a meteorite have ever been found. Over the last century, the mysterious nature of the event has prompted a wide array of speculation and investigation, including from science fiction writers and voluntary researchers. Some have even explained Tunguska as a nuclear explosion triggered by aliens. Join us for a presentation by Dr. Andy Bruno from Northern Illinois University, where he will recount the intriguing history of the Tunguska event and the investigations into it.
