CERN scientists prepare to restart the Large Hadron Collider, the largest and most powerful particle accelerator. It is to run it at a higher energy than before, when it detected a subatomic particle that may be the elusive Higgs boson.
The effort to salvage the Costa Concordia cruise ship, which ran aground and capsized off the coast of Italy on January 13, 2012, killing 32 people, is chronicled.
Sinkholes are examined. The collapses can be gradual or sudden; and occur when carbon dioxide in the air dissolves in rainwater and forms an acid that weakens limestone and other water-soluble rocks beneath the soil.
Archaeologists and engineers employ ancient Roman techniques to build an elevator and trap-door system similar to those used in the Colosseum, where wild animals emerged, as if by magic, from beneath the floor.
A look at the ancient city of Petra in Jordan, which was carved from stone and possessed an ingenious water-conduit system. Archaeologist and sculptors join forces to carve a temple-tomb to learn how the people of Petra built the city.
Architects and engineers investigate the secrets behind Istanbul's Hagia Sophia, which has survived on one of the world's most active seismic faults since it was built in 537 A.D.
An exploration of mathematics, including where it comes from and why it explains the physical world; and whether it's a human invention or a hidden language of the universe.
The story of the Hubble Space Telescope, which was launched into orbit in 1990. It since has provided stunning images; helped astronomers determine the age of the universe; and advanced the understanding of dark energy and cosmic expansion
The wreckage of WWII-era German submarine U-166, which sank in the Gulf of Mexico in 1942, is examined. The U-boat was part of Operation Drumbeat, a Nazi operation that targeted East Coast cities and merchant ships.
How carbon emissions are impacting the world's oceans. Included: a coral garden in Papua New Guinea that could offer a preview of what the seas will be like in a half-century.
NOVA captures New Horizons' historic flyby of Pluto, the culmination of the spacecraft's nine-year, three-billion-mile journey to reveal the first ever detailed images of this strange, icy world at the very edge of our solar system.
Four years after one of history's worst nuclear accidents, NOVA reveals the minute-by-minute story of the Fukushima nuclear crisis and its ongoing aftermath, told by the brave workers who stayed behind as an earthquake and tsunami crippled the plant.
160 years ago, the Franklin Expedition to chart the Northwest Passage vanished. NOVA is on board as a Canadian team makes a breakthrough discovery of one of Franklin's lost ships--a vital new clue to the fate of the ill-starred expedition.
How life emerged in North America; and why the continent was home to many iconic dinosaurs, including the T. rex. Included: a trip to the Badlands of North Dakota and desert wilderness of southern Utah highlights dinosaur discoveries.
