The Mystery of UFOs

This updated edition asks some great questions. How many UFO sightings are still unexplained? What happened at Roswell, New Mexico, in 1947? Who were the "real" Men in Black? Some things are so strange that they cannot be explained. The 'Can Science Solve?' books present some of the most puzzling mysteries that logic and science have yet to solve. This series explains the connection between science and natural phenomena and how science can be used to try to explain mysteries.
