As we look at the world around us, we think we're seeing things as they really are. But in fact, our human senses can only perceive less than 1% of what's actually there. The rest is invisible. Every day, unseen rays and waves bombard us. All around us there's an infinite, invisible ecosystem of wondrous and sometimes terrifying microorganisms struggling to survive. With the naked eye we can't see the things that are too fast or too slow, too big or too small...until now. In this fascinating documentary, we count down the 40 most amazing things you can't see with the human eye. We use the latest in cutting edge technology, and state of the art CGI animation to reveal the astonishing reality of the invisible world around us. TVPG VL | CC

In 1980, three young military men were sent into a UK forest to investigate strange lights. They reportedly encountered a spacecraft of unknown origin. When one of the men touched it, he claims to have received telepathically a long sequence of binary code, which he later wrote down and translated.

Geologist Scott Wolter has reason to believe America has its very own Stonehenge in New Hampshire. With the help of a young man who discovered an amazing connection between America's Stonehenge and Stonehenge in England, Wolter explores the possibility that the ancient Phoenicians are connected to both of these megalithic sites. At America's Stonehenge, he uncovers many clues, including a sacrificial table and a mysterious message carved on a stone in ancient script that helps advance this provocative theory.

A man shows up at Scott Wolter's lab with a 500-pound discovery. In the flatbed of his truck is a large boulder he pulled from the Arkansas River, inscribed with a mysterious bull symbol. Wolter's investigation into who carved the stone and for what ritualistic purpose ultimately reveals a connection between the ancient Egyptian cult of the Apis bull, the mysterious religion known as Mithraism and a party of pre-Columbian explorers to Oklahoma's panhandle. In the end, carvings in a cave in America's Heartland shed light on an ancient connection that could prove a group of religious outcasts made it to America in pre-Columbian times.

Southerners have a certain style, language and way of life. But what many people don't know is that America itself was made in the South. This two-hour special journeys to the real South for an informative and sometimes lighthearted look at its distinctive cultures, characteristics and influences on our country's history. Narrated by Charlie Daniels, well-known Southerners--Jeff Foxworthy, Trace Adkins, Ty Pennington, James Carville, Ricky Scaggs, Michael Waltrip, Bobby Bowden, Lyrnyrd Skynryd, Herschel Walker, Al Bell, and others--weigh in on cornerstones of Southern life: barbecue and moonshine, hunting and fishing, college football and the Grand Ol' Opry.

This two-hour special offers an in-depth look at the critical 24-hour period after news of Japan's attack on U.S. soil in 1941 reached the President. Drawing on exhaustive research and new information provided by the FDR Library, the special gives a rare and surprising glimpse at the man behind the Presidency and how he confronted the enormous challenge of transitioning the nation from peace to war. There was no direct phone line between Pearl Harbor and the White House. As information slowly trickled in and word of the bombing got out, panic gripped the White House. FDR's unique style of leadership enabled him to galvanize the American people in the wake of a grave and potentially demoralizing attack. The special features acclaimed historian Steven M. Gillon, author of the recently released Pearl Harbor: FDR Leads the Nation Into War. TVPG VL | CC

Easter Island, the Mayan ruins, and the abandoned pueblos of Chaco Canyon all stand as haunting monuments to extinct civilizations. Each of these societies collapsed because of man-made ecological disasters. Each confronted choices chillingly similar to the ones we face today. Are we living in the last century of our civilization? Many of the world's top scientists say yes, unless we quickly learn the lessons of the past. This two-hour special examines the current path of our modern world. Top U.S. Army, intelligence, and policymakers who have modeled a scenario of the next century say that if we continue on this trajectory, over the next hundred years the "perfect storm" of population growth, resource depletion, climate change, terrorism and disease will converge in an unstable world with catastrophic results. What lessons of the past must we heed to survive? TVPG VL | CC

On October 26, 1994, the U.S. government made their first official acknowledgement of Area 51. Six months later, nearly 4,000 acres of previously public land surrounding the base were closed. Now, over a decade later, satellite photos reveal new buildings, towers and runways finishing construction. Secret flights with blacked-out windows bring passengers from Las Vegas. And security surrounding the perimeter of the base is tighter than ever. The team heads to the epicenter of UFO and military conspiracy theories to visit new vantage points, speak with former base employees, and search the skies above America's most top-secret facility.

What happens when a UFO crashes? Some experts claim that the UFO wreckage and even the pilots are transported to a top-secret facility in Dayton, Ohio called "Hangar 18" located on Wright Patterson Air Force Base. Declassified Government documents prove that the "disk" from the famous Roswell event and fragments of other mysterious crashes were shipped to Wright Patterson. Hear stories involving elected officials, UFO researchers, and former base employees, some of whom are going on the record regarding "Hangar 18." They spin a tale of flying saucer debris, alien bodies, cryogenic chambers and a vast underground network that may hold the secrets to the UFO mystery.

In April 1897--50 years before the alleged UFO crash in Roswell, New Mexico--a mysterious airship crash rocked the small town of Aurora, Texas...or at least, that's how the legend goes! The tale includes the wreckage from the ship, a funeral for the dead "alien" pilot, and thousands of witnesses from across the country. And the Aurora crash allegedly took place five years before the Wright Brothers flew at Kitty Hawk, so whatever was in the air was not manmade. Eyewitness accounts of the crash, mysterious metal found at the site, and the hunt for the only known alien graveyard are all combined into a story that has even the most adamant debunkers baffled. Is this the case that finally proves that UFOs are real? Join us as we separate fact from fiction. TVPG VL | CC

A man shows up at Scott Wolter's lab with a 500-pound discovery. In the flatbed of his truck is a large boulder he pulled from the Arkansas River, inscribed with a mysterious bull symbol. Wolter's investigation into who carved the stone and for what ritualistic purpose ultimately reveals a connection between the ancient Egyptian cult of the Apis bull, the mysterious religion known as Mithraism and a party of pre-Columbian explorers to Oklahoma's panhandle. In the end, carvings in a cave in America's Heartland shed light on an ancient connection that could prove a group of religious outcasts made it to America in pre-Columbian times.
