In 1977, a remote Brazilian island was visited nightly by strange flying objects, leaving people with bizarre puncture marks and blood loss. What happened?

Most contend the world's most famous magician died when one of his tricks went fatally wrong, but new evidence suggests that his death may have been no accident.

Based on Einstein's theories and countless scientific studies, we'll find out how these visitors might bridge the vast distances between the stars. And if they could survive such hazardous journeys, are they flesh and blood or intelligent machines?

As science turns towards augmenting humanity with technology, theorists suggest that we are merely following the path of our alien creators.

Chasing accounts of giant skeleton discoveries, Jim and Bill Vieira follow in the footsteps of Abraham Lincoln, who was fascinated by tales and legends of ancient colossi.

A monument carved out of rock and a monster-sized super-dome are the feats of engineering defy explanation, yet they were actually built thousands of years ago. The Great Pyramid was the tallest structure on earth for over 4,000 years.

Since an influx of Chinese immigrants to America in the mid 1800s, Americans have devoured Chinese take-out. But have you ever wondered what's really in an egg roll? And did you know a fortune cookie can actually make you rich?

This time on River Hunters, presenter Rick Edwards and master detectorist Beau Ouimette team up to hunt for relics from the 14th Century bloody and brutal clashes between the English and the Scottish.

In 1938, hundreds of mysterious stone disks were found in a cave in China. Some believe the stones are proof of contact with an alien race. Fact or fiction?

The Alaska Triangle--the region between Anchorage, Juneau and Barrows--has a disappearance rate sixteen times the national average, and scientists are entirely incapable of explaining why.

Explore how violent events shaped the universe, including the disaster that turned Mars into a barren and hostile desert.

Ancient astronaut theorists look at the Aborigine mythos of Dreamtime, and ask if these stories hold the proof that aliens created life on Earth.

The castles and dungeons of the Hittites are hidden beneath the sandy lunar landscape of Cappadocia. Why did this ancient empire fall?

Treasure Hunters Suggs and Stephen Taylor are on the trail of an iconic Mark IX Spitfire in Belgium.

US airline pilots are reporting near mid-air collisions with UFOs. Elizondo hears a never-before-told account from a major legacy airline pilot whose report of a glowing orange sphere while in the cockpit over Arizona is backed up by photo evidence.
