Petra - Lost City of Stone (#4205H) Duration: 55:41 STEREO TVPG
More than 2000 years ago, the thriving city of Petra rose up in the bone-dry desert of what is now Jordan. An oasis of culture and abundance, the city was built by wealthy merchants whose camel caravans transported incense and spices across hundreds of miles from the Arabian Gulf. They carved spectacular temple-tombs into its soaring cliffs, raised a monumental Great Temple at its heart, and devised an ingenious system that channeled water to vineyards, bathhouses, fountains, and pools. But following a catastrophic earthquake and a slump in its desert trade routes, Petra's unique culture faded and was lost to most of the world for nearly a thousand years.
Now, in a daring experiment, an archaeologist and sculptors team up to carve an iconic temple-tomb to find out how the ancient people of Petra built their city of stone. And beyond Petra's city of the dead, scientists using remote sensors and hydraulic flumes discover a city of the living-complete with a water system that not only supplied 30,000 people with enough to drink, but also filled bathhouses, fountains, and pools with such abundance that some scholars believe this desert metropolis may have been the Las Vegas of the ancient world. The race is on to discover how these nomads created this oasis of culture in one of the harshest climates on earth, and ultimately, why Petra disappeared.
Great Cathedral Mystery (#4105H) Duration: 55:06 STEREO TVG

Invisible Universe Revealed (#4208H) Duration: 56:46 STEREO TVG
25 years ago, NASA launched one of the most ambitious experiments in the history of astronomy: the Hubble Space Telescope. In honor of Hubble's landmark anniversary, Nova tells the remarkable story of the telescope that forever changed our understanding of the cosmos and our place in it.
From its inception through its early days, when a one-millimeter engineering blunder turned the telescope into an object of ridicule, to the five heroic astronaut missions that returned Hubble to the cutting edge of science, Nova hears from the scientists and engineers on the front line who tell the amazing Hubble story as never before. This single telescope has helped astronomers pinpoint the age of the universe, revealed the birthplace of stars and planets, advanced our understanding of dark energy and cosmic expansion, and uncovered black holes lurking at the heart of galaxies. For more than a generation, Hubble's stunning images have brought the beauty of the heavens to millions, revealing a cosmos richer and more wondrous than we ever imagined. Join Nova for the story of this magnificent machine and its astonishing discoveries.
Cyberwar Threat (#4217H) Duration: 56:46 STEREO TVPG
Through startling, previously unreported detail, delve into the chilling new reality of cyberwar, in which cyber weapons can inflict physical damage on our factories, power plants and pipelines - leaving us vulnerable to crippling attacks.
Deadliest Earthquakes (#3801H) Duration: 55:31 STEREO TVPG (Secondary audio: DVI)
In 2010, epic earthquakes all over the planet delivered one of the worst annual death tolls ever recorded. The deadliest strike was in Haiti, where a quake just southwest of the capital, Port-au-Prince, killed more than 200,000, reducing homes, hospitals, schools, and the presidential palace to rubble. In exclusive coverage, a Nova camera crew follows a team of US geologists as they first enter Haiti in the immediate aftermath of the tragedy. It is a race against time as they hunt for crucial evidence that will help them determine exactly what happened deep underground and what the risks are of a new killer quake. Barely a month after the Haiti quake, Chile was struck by a quake 100 times more powerful, unleashing a tsunami that put the entire Pacific coast on high alert. In a coastal town devastated by the rushing wave, Nova follows a team of geologists as they battle aftershocks to measure the displacement caused by the earthquake. Could their work, and the work of geologists at earthquake hot-spots around the US, one day lead to a breakthrough in predicting quakes before they happen? Nova investigates new leads in its investigation of a deadly scientific conundrum.

Colosseum - Roman Death Trap (#4206H) Duration: 55:21 STEREO TVPG-V
One of the ancient world's most iconic buildings, the Colosseum is a monument to Roman imperial power and cruelty. Its graceful lines and harmonious proportions concealed a highly efficient design and advanced construction methods that made hundreds of arches out of 100, 000 tons of stone. But this building is more than just an architectural giant - in its heyday it was filled with unbelievable spectacles and 50,000 cheering fans. In its elliptical arena, tens of thousands of gladiators, slaves, prisoners, and wild animals met their deaths. Ancient texts report lions and elephants emerging from beneath the floor, as if by magic, to ravage gladiators and people condemned to death. Then, just as quickly, the Colosseum could be flooded with so much water that ships could engage in sea battles to the delight of the crowd. Could these legends be true, or are they just myth?
Now, with extraordinary access to one of the world's most protected world heritage sites, archaeologists and engineers are teaming up to recreate ancient Roman techniques to build a 25-foot lifting machine and trap door system capable of releasing a wolf into the Colosseum's arena for the first time in 1500 years. To do it, they will have to decipher ghost-like impressions left on the crumbling walls of the Colosseum's basement by the original lifts and then transform them into working plans for construction. Do they have what it takes to replicate the innovation and ingenuity of the Romans?
Nazi Attack On America (#4210H) Duration: 56:46 STEREO TVPG
Long before 9/11, a far deadlier, little-known attack from the ocean depths struck our shores, lasting three-and-a-half years and claiming 5,000 lives. Now, famed undersea explorer Bob Ballard, discoverer of the Titanic, investigates the wreck of one of the attack craft, a German submarine that lies at the bottom of the gulf just a few miles off New Orleans. U-166 was part of Operation Drumbeat, a highly successful U-boat operation that caught East Coast cities and shipping almost completely unprepared. With state-of-the-art survey gear, Ballard probes the wreck and unravels a dramatic mystery in the official story of the sub's sinking.

Building Wonders: Hagia Sophia - Istanbul's Ancient Mystery (#4204H) Duration: 55:21 STEREO TVG
The soaring dome of Hagia Sophia dominates Istanbul's skyline. Whether serving as Christian church, Islamic mosque, or secular museum, this magnificent building has inspired reverence and awe. For eight hundred years, it was the largest enclosed building in the world; the Statue of Liberty can fit beneath its dome with room to spare. How has it survived its location on one of the world's most active seismic faults, which has inflicted a dozen devastating earthquakes since it was built in 537 AD? As Istanbul braces for the next big quake, a team of architects and engineers is urgently investigating Hagia Sophia's seismic secrets.
Nova follows the team's discoveries as they examine the building's unique structure and other ingenious design strategies that have insured the dome's survival. At the climax to the show, the engineers build a massive 8-ton model of the building's core structure, place it on a motorized shake table and hit it with a series of simulated quakes, pushing it collapse -a fate that the team is determined to avoid in the real world. The Unshakeable Hagia Sophia is a detective story that reveals how this architectural wonder has proven so resilient for so long, and how it came to serve as a proud expression for the great civilizations that adopted it as a symbol.
