Aliens and UFOs: Making Sense of Myths, pt. 4

In the final episode of our series about myths and legends, we’re launching our imaginations into outer space! Monster expert Emily Zarka tells us about her favorite alien and why aliens fascinate so many people. In the Hoax Hunters season finale, Marc and Sanden bring us a UFO spoof. Plus, scientists give us the lowdown on the real quest for extraterrestrial life — we haven’t found any... yet. And, planets and moons compete for the title of ‘most likely to have life’. A new moment of um keeps us outside the atmosphere: why does space look so dark if the sun is so bright? Today’s episode is sponsored by The American Dental Association (ada.org/brains).
