UFO is a general term for objects sighted in the sky which are not readily identifiable, either by sight or with the assistance of technology such as radar.The existence of flying saucers, as they are popularly known, has been neither proved nor disproved, but they remain one of the only explanations for some of the most mysterious UFO sightings known.

Bigfoot, also known as sasquatch, is the name given to an ape-like creature that some people believe inhabits forests, mainly in the Pacific Northwest region of North America. Bigfoot is usually described as a large, hairy, bipedal humanoid. The term sasquatch is an anglicized derivative of the Halkomelem word sasq'ets. Most scientists discount the existence of Bigfoot and consider it to be a combination of folklore, misidentification, and hoax, rather than a living animal, because of the lack of physical evidence and the large numbers of creatures that would be necessary to maintain a breeding population.

It is much clearer in black-and-white negative than in its natural sepia color.

#6 Jack the Ripper
Jack the Ripper is the fictional name given to a serial killer of prostitutes in the impoverished areas around Whitechapel during the late 19th century.

The sculpture continues to provide a diversion for cryptanalysts, both amateur and professional, who are attempting to decrypt the final section.

The case remains the only unsolved air piracy in American aviation history.
#1 Stonehenge
The great mystery of Stonehenge is not when it was built, but why. This circle of giant standing stones in the south of England is believed to have been built between 3000 and 2000 BC, and carbon dating is being used to narrow down this range of potential dates. But what is unknown is the purpose of the stones, and why they were transported and built at a time before any sort of building technology.
