Nova - Season 44 (2017)

Weighing 54,000 gross tons and stretching over two football fields, the Seven Seas Explorer is no ordinary boat. Join pioneering shipbuilders as they endeavor to build the ultimate cruise ship. It will be decked with the finest gold, marble, and crystal and designed to offer guests the roomiest accommodations of any commercial cruise ship. However, engineering opulence is no easy feat. NOVA follows a pioneering team of ship builders as they embark on what is advertised to be a milestone in maritime engineering.

The centuries old Japanese art form has gone high tech. Building with examples in biology and applying sophisticated mathematics, computer software and good old fashion imagination it looks like any structure can be folded and practical applications are everywhere.

A look at several recent train crashes, their causes and a technological solution which should make such events occur much less often.

For centuries, the Lithuanian city of Vilnius was one of the most important Jewish centers in the world, earning the title "Jerusalem of the North," until the Nazis destroyed it. About 95% of its Jewish population of Vilna, its name in Hebrew and Yiddish, was murdered and its synagogues and institutions were reduced to ruins. The Soviets finished the job, paving over the remnants of Vilna's famous Great Synagogue, for example, so thoroughly that few today know it ever existed. Now, an international team of archaeologists are trying to recover this lost world. They ...

An international team of engineers races to construct a gargantuan dome to contain the lingering radioactive materials and crumbling remains of the Chernobyl nuclear reactor, decades after being the site of the world's worst nuclear disaster.

Experts reconstruct and test China's first super-weapon, the chariot, which dominated the battlefields for more than 1000 years.

In this special report, NOVA investigates the water disaster in Flint and unravels a disturbing truth about the vulnerabilities of water systems across the country. Discover the delicate intricacies of water chemistry, the biology of lead poisoning, and the engineering challenge of replacing this ravaged infrastructure.

On August 21, 2017, millions of Americans witnessed the first total solar eclipse to cross the continental United States in 99 years. As in all total solar eclipses, the moon blocked the sun and revealed its ethereal outer atmosphere - its corona - in a wondrous celestial spectacle. While hordes of citizens flocked to the eclipse's path of totality, scientists, too, staked out spots for a very different reason: to investigate the secrets of the sun's elusive atmosphere. During the eclipse's precious seconds of darkness, they gathered new clues on how our sun works, ...

For over a decade, the Cassini space probe has been sending dazzling images of Saturn's breathtaking rings and mysterious moons. Join Nova on a suspenseful ride during Cassini's final hours as it dives into Saturn's atmosphere.

Discover what it was like to be a knight in shining armor and follow the historic manufacturing process. Master armorers re-engineer the Greenwich armor - considered some of the greatest armor ever made - and then put it to the test.

Who built Stonehenge and why? Groundbreaking archaeological digs have revealed major new clues about Britain's enigmatic 5,000-year-old site and the people who constructed it.

The architectural design of Beijing's ancient complex of palaces and temples enabled it to survive centuries of earthquakes.

Volcanologists search for an elusive volcanic mega-eruption that plunged the medieval earth into a deep freeze. Investigate the geologic evidence from Greenland all the way to Antarctica to identify the 750-year-old culprit.

Killer Hurricanes pursues the riddle of an 18th century Caribbean superstorm that killed 20,000, the highest known death toll of any single weather event. To reconstruct its epic scale and investigate what made it so devastating, NOVA joins historians and storm sleuths as they track down clues in eyewitness chronicles, old ruins, and computer simulations.

Geologists examine extreme terrain on Iceland, the Scablands in Washington State, and submerged in the English channel to see if they were created by the same process, a sudden titanic flood.

Why some animals have extreme armaments, including claws, horns, fangs and stings.

Join NOVA to witness the brainpower of birds. Long mocked as empty-headed, our feathered friends hide surprisingly acute intelligence. But how smart are they? Watch as scientists test avian aptitude and challenge our basic notions of intelligence.

Investigate how an asteroid vanquished the dinosaurs 66 million years ago. Join scientists as they drill into the impact crater and, for the first time, reconstruct the hell on earth that unfolded in the minutes, hours and months after the impact.
