Extreme Cave Diving (#3705H) Duration: 55:46 STEREO TVG (Secondary audio: DVI)
Follow the charismatic Dr. Kenny Broad as he dives into Blue Holes -- underwater caves that formed during the last ice age when sea level was nearly 400 feet below what it is today. They are Earth's least explored and perhaps most dangerous frontiers. With an interdisciplinary team of climatologists, paleontologists and anthropologists, Broad investigates the hidden history of Earth's climate as revealed by finds in this spectacularly beautiful "alternate universe."
Making North America: Origins (#4220H) Duration: 56:16 STEREO TVG
See the epic 3-billion-year story of how our continent came to be. From palm trees that once flourished in Alaska to huge eruptions that nearly tore the Midwest in two, discover how forces of almost unimaginable power gave birth to North America.

Meteor Strike (#4013H) Duration: 56:46 STEREO TVPG
A blinding streak of light screaming across the Russian sky, followed by a shuddering blast strong enough to damage buildings and send more than 1000 people to the hospital. On the morning of February 15th, a 7000 ton asteroid crashed into the Earth's atmosphere, exploded and fell to earth across a wide swath near the Ural mountains. According to NASA, the Siberian Meteor, which exploded with the power of 30 Hiroshima bombs, was the largest object to burst in the atmosphere since a 1908 event near Siberia's Tunguska river. That time there were few eyewitnesses and no record of the event except for thousands of acres of flattened trees. This time however the event was captured by countless digital dashboard cameras, which have lately become a common fixture in Russian autos and trucks.
Within days, armed with this unprecedented crowd-sourced material, Nova crews hit the ground in Russia along with impact scientists as they hunt for debris from the explosion and clues to the meteor's origin and makeup. To understand how lucky we were this time, we explore even greater explosions in the past, from Tunguska to the asteroid that extinguished the dinosaurs 65 million years ago. This episode puts it all together and asks: Is our solar system a deadly celestial shooting gallery - with Earth in the cross-hairs? What are the chances that another, even more massive asteroid is heading straight for us? Are we just years, months or days away from a total global reboot of civilization, or worse?

Roman Catacomb Mystery (#4104H) Duration: 54:16 STEREO TVPG
Beneath the streets of Rome lies an ancient city of the dead known as the Catacombs -- a labyrinth of tunnels, hundreds of miles long, lined with tombs. Now, Nova goes inside a previously-unknown complex within the tunnel system: a mysterious mass grave, locked away for nearly 2000 years. Nova's forensic investigation opens up fascinating new insights into the daily life and health of Roman citizens at the heyday of its mighty empire.

Building The Great Cathedrals (#3711H) Duration: 55:31 STEREO TVG (Secondary audio: DVI)
Carved from 100 million pounds of stone, soaring effortlessly atop a spiderweb of masonry, Gothic cathedrals are marvels of human achievement and artistry. But how did medieval builders reach such spectacular heights? Consuming the labor of entire towns, sometimes taking 100 years to build, these architectural marvels were crafted from just hand tools and stone. Many now teeter on the brink of catastrophic collapse. To save them, an international team of engineers, architects, art historians and computer scientists searches the naves, bays, and bell towers for clues to how the dream of these heavenly temples on earth came true. Nova's teams perform hands-on experiments to investigate and reveal the architectural secrets that the cathedral builders used to erect their soaring, glass-filled walls. This program reveals the hidden formulas, drawn from the pages of the Bible itself, that drove medieval builders ever upward.

Secret Tunnel Warfare (#4301H) Duration: 56:46 STEREO TVPG
Join archaeologists who reveal traces of World War I's most devastating, ultra-secret tunneling operation. During WWI, the Allies devised a devastating plan, planting 600 tons of explosives in secret tunnels driven under German trenches. Join Nova to uncover traces of the operation and learn why it failed to break the lethal deadlock of trench warfare.
Quest for Solomon's Mines (#3716H) Duration: 55:46 STEREO TVG (Secondary audio: DVI)
Inspired by the Bible's account of the splendor of his temples and palaces adorned in glittering gold and copper, countless treasure-seekers have set off in search of King Solomon's mines. They have trekked through burning deserts and scaled the forbidding mountains of Africa and the Levant. Yet to date, the evidence that's been claimed to support the existence of Solomon and other early kingdoms in the Bible has been highly controversial. In fact, there is so little physical evidence of the kings who ruled Israel and Edom that many contend that they are no more real than King Arthur. During the summer of 2010, Nova and National Geographic embarked on two groundbreaking expeditions to expose new clues buried in the pockmarked desert of Jordan: the ancient remnants of a mass industrial-scale copper mine and a 3000-year-old message from the past with the words "slave," "king" and "judge." These cutting-edge investigations illuminate the legend of Solomon and reveal the source of the great wealth that powered the first mighty Biblical kingdoms.
