NASA's Unexplained Files

The second season of NASA's Unexplained Files is revisiting the space agency's archives to reveal countless more mysteries and unusual encounters, discoveries and sightings that NASA has experienced over the years. For decades NASA has been tasked with exploring the unknown. The agency has reached beyond the bounds of Earth in search of knowledge to benefit mankind - launching scientists into space and spacecrafts to the limits of the solar system. What those missions have uncovered are sometimes disturbing anomalies that have perplexed the world's finest scientific minds. Each episode of NASA's Unexplained Files scrutinises evidence, explores possible explanations and considers testimonies from NASA insiders, scientists, astronauts and others who have witnessed these strange phenomena. Often inexplicable, bizarre and barely believable, the stories featured in NASA's Unexplained Files are made all the more unusual in that they come from the most credible scientific organisation in the world.
