Nova Season 42 Episodes

21 Episodes 2015 - 2024

Episode 1

Big Bang Machine

Wed, Jan 14, 201554 mins

On July 4, 2012, scientists at the giant atom smashing facility at CERN announced the discovery of a subatomic particle that seems like a tantalizingly close match to the elusive Higgs Boson, thought to be responsible for giving all the stuff in the universe its mass. Since it was first proposed nearly 50 years ago, the Higgs has been the holy grail of particle physicists: finding it completes the "standard model" that underlies all of modern particle physics. Now CERN's scientists are preparing for the Large Hadron Collider's second act, when they restart the history-making collider, running at higher energy -- hoping for the next great discovery that will change what we know about the particles and forces that make up our universe.

Sunken Ship Rescue

Wed, Jan 21, 201554 mins

NOVA follows the epic operation to secure, raise and salvage the Costa Concordia cruise ship, which ran aground and capsized off the coast of Italy on January 13, 2012, killing 32 people. The wreck stretches the length of three football fields, weighs 45,000 tons and lies half submerged on the site of a protected reef, with a 160-foot-long hole in its hull. Moving it from its precarious perch on the edge of an underwater cliff will be a huge technical and logistical challenge. Now, NOVA joins a team of more than 500 divers and engineers working around the clock as they attempt the biggest ship recovery project in history.

Sinkholes-Buried Alive

Wed, Jan 28, 201554 mins

In Tampa, Florida, in February 2013, a giant hole opened up under the bedroom floor of Jeffrey Bush, swallowing the 36-year-old as he slept. His body was never found. Bush was a victim of a sinkhole -- a growing worldwide hazard that lurks wherever limestone and other water-soluble rocks underpin the soil. When carbon dioxide in the air dissolves in rainwater, it forms a weak acid that attacks the soft rocks, riddling them with holes like Swiss cheese. Sinkholes can occur gradually when the surface subsides into bowl-shaped depressions or suddenly, when the ground gives way -- often catastrophically. Sinkholes have swallowed highways, apartment buildings, horses, camels, even golfers, with monster-size holes cracking the earth from Siberia to Louisiana. With compelling eyewitness video of dramatic collapses, and following scientists as they explore the underlying forces behind these natural disasters, NOVA travels the globe to investigate what it's like to have your world vanish beneath your feet.

Colosseum: Roman Death Trap

Wed, Feb 11, 201554 mins

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. 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. Could these legends be true? Now, with access to one of the world's most protected world heritage sites, archaeologists and engineers team up to re-create 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 1,500 years.

Petra: Lost City of Stone

Wed, Feb 18, 201554 mins

More than 2,000 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 who carved spectacular temple-tombs into its cliffs, raised a monumental Great Temple 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 1,000 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.

Hagia Sophia: Istanbul's Mystery

Wed, Feb 25, 201554 mins

Istanbul's magnificent Hagia Sophia has survived on one of the world's most active seismic faults, which has inflicted a dozen devastating earthquakes since Hagia Sophia was built in 537 AD. As Istanbul braces for the next big quake, a team of architects and engineers is 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. The engineers build a massive eight-ton model of the building's core structure, place it on a motorized shake table and hit it with a series of simulated quakes.

The Great Math Mystery

Wed, Apr 15, 201554 mins

NOVA leads viewers on a mathematical mystery tour -- a provocative exploration of math's astonishing power across the centuries. We discover math's signature in the swirl of a nautilus shell, the whirlpool of a galaxy and the spiral in the center of a sunflower. Math was essential to everything from the first wireless radio transmissions to the prediction and discovery of the Higgs boson and the successful landing of rovers on Mars. But where does math get its power? Astrophysicist and writer Mario Livio, along with a colorful cast of mathematicians, physicists and engineers, follows math from Pythagoras to Einstein and beyond, all leading to the ultimate riddle: Is math an invention or a discovery? Humankind's clever trick or the language of the universe?

Invisible Universe Revealed

Wed, Apr 22, 201554 mins

Twenty-five 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. But amazingly, when the telescope first sent images back to earth, it seemed that the entire project was a massive failure; a one-millimeter engineering blunder had turned the billion-dollar telescope into an object of ridicule. It fell to five heroic astronauts in a daring mission to return 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.

Lethal Seas

Wed, May 13, 201554 mins

A deadly recipe threatens the survival of countless creatures throughout Earth's oceans. We've known for years that oceans absorb about a quarter of the carbon dioxide in our atmosphere.

As a result, the skeletons and shells of marine creatures that form the foundation of the web of life are dissolving. Follow scientists who are seeking solutions and making breakthrough discoveries, including a unique coral garden in Papua New Guinea that offers a glimpse of what the seas could be like in a half-century. Can experts crack the code of a rapidly changing ocean -- before it's too late?
