Since it explored Pluto in 2015, the New Horizons spacecraft has been zooming toward NASA’s most distant target yet. Join the mission team as the probe attempts to fly by Ultima Thule, an object 4 billion miles from Earth.

Einstein called it “spooky action at a distance,” but today quantum entanglement is poised to revolutionize technology from computers to cryptography. Physicists have gradually become convinced that the phenomenon—two subatomic particles that mirror changes in each other instantaneously over any distance—is real.

Journey to Hawaii's Kilauea volcano, which sent rivers of lava through communities and into the sea when it erupted in 2018. A group of scientists and locals investigate the spike in volcano activity that turned paradise into an inferno.

New archeological evidence sheds light on the stunning engineering of the Great Pyramid of Giza.

With new technologies, NASA and private companies are promising a new renaissance in space travel.

In the shadow of Vesuvius and Pompeii, a lesser-known volcano puts the city of Naples at risk.

The Dead Sea is dying: Since 1976, its level has dropped more than 100 feet, leaving its coastline pockmarked with thousands of sinkholes. But after more than a decade of research and debate, scientists, engineers, and political leaders have come up with a daring plan: connect the Red Sea to the Dead Sea by way of a massive desalination plant. If it’s successful, the project could not only revive the sea, but also help ease political tensions and water shortages in the region. NOVA follows this unprecedented endeavor—perhaps the world’s largest water chemistry experiment—as scientists race to save the Dead Sea and bring water to one of the driest regions on Earth.

From the front line of the Camp Fire, the deadliest wildfire in California history, NOVA tells the stories of residents who had to flee for their lives during the 2018 fire season. Scientists racing to understand what’s behind the rise of record-breaking megafires across the American West take to the forest, and even a fire lab, in search of answers. They investigate how forestry practices, climate change, and the physics of fire itself play a role in the dramatic increase in wildfires in recent decades.

Horse riding played a key role in human expansion and civilization. Scientists use archeology and genetics to uncover clues about the first horse riders and how they shaped the world.

Bioarchaeologists investigate a ninth-century mass grave in a rural English village. Will the remains unlock the mystery of the “Great Heathen Army,” a legendary Viking fighting force that once invaded England?

Fifty years after humans first stepped foot on the moon, engineers, scientists and entrepreneurs engage in new discoveries to make life on the moon a reality.

The rocky planets have similar origins, but only one supports life. Was it always this way?

Before it was the dry Red Planet, Mars was a wet world that may have had the ingredients for life.

Jupiter's massive gravitational force has made it both a wrecking ball and a protector of Earth.

Nasa's Cassini reveals the mysteries of Saturn's rings and new hope for life on one of its moons.

Beyond the bizarre, icy worlds of Uranus and Neptune, Pluto dazzles with its mysterious ocean.

Sixty-six million years ago, an asteroid wiped out the dinosaurs in a fiery global catastrophe. But we know little about how their successors, the mammals, recovered and took over the world. Now, hidden inside ordinary-looking rocks, an astonishing trove of fossils reveals a dramatic new picture of how rat-sized creatures ballooned in size and began to evolve into the vast array of species

In 2018, Italy’s Morandi Bridge collapsed, tragically killing 43 people. For 50 years, the iconic bridge had withstood the elements—and stress from ever-increasing traffic. What went wrong that fateful day? And how can new engineering technology protect bridge infrastructure to prevent such tragic failures in the future?

As self-driving cars take to the streets, investigate how they work, and if they are safe.

New technologies unravel the Dead Sea Scrolls’ mysteries and uncover million-dollar fakes.

A visit to Florence, Italy to explore how Leonardo da Vinci used science, from human dissections to innovative painting techniques, to create his artwork.

Violence is all over the news. But some say we’re living in the most peaceful time in history. Journey through time and the human mind to investigate whether—and how—violence has declined. And witness how people are working to stop violence today.

How do you study giant armadillos when hardly anyone has ever seen one? Or figure out if a whale is losing weight—without getting too close? Camera and drone technologies are allowing scientists to watch animals more closely than ever before, without disturbing them. Scientists in India are using thousands of camera trap photos to track tigers' movements. In Canada, caribou outfitted with collar cams show conservationists which habitats they rely on throughout the winter. Capturing everything from the unexpected to the comical, these technologies are giving wildlife managers insights that could ultimately help them fight extinction and habitat loss.
