The Out of This World UFO Show with Neil deGrasse Tyson

There are thousands of sightings of Unidentified Flying Objects every year, but why do so many people assume they are aliens visiting from another galaxy? Most UFOs end up being identified as clouds or other natural phenomena, or man-made objects such as balloons or aircraft.

Neil and comedian co-host Eugene Mirman discuss the tricks the human brain can play on our perception, the physics of space travel, and science fiction movies that depict alien spaceships. Neil interviews James McGaha, UFO investigator, about the many unusual things that can appear in the sky, and SETI researcher Seth Shostak calls in for a chat about alien visitations. With science as your co-pilot, the truth is always out there.
