Dwelling beneath Naples, Campi Flegrei is less famous than Mount Vesuvius. But, by looking at its pyroclastic flows beneath the city, scientists suspect this volcano could be exponentially more powerful.

Samples of carbon dioxide from Mt. Vesuvius can reveal how close magma is to the volcano's surface. To collect them, researchers descend into Vesuvius' 1,000-foot-deep crater.

In the shadow of Italy’s Vesuvius, a lesser-known volcano rumbles: Campi Flegrei. If it erupts, millions of lives could be at risk. Scientists explore its unique geology and develop a warning system that could prevent Naples becoming the next Pompeii.

Returning a rocket safely back to the launch site involves a series of complex steps which begin on the edge of space, when still traveling at over 3,500 miles per hour.

New technologies are making rockets cheaper and more powerful than ever before. As companies like SpaceX and Virgin Galactic make space more accessible, and NASA returns to crewed spaceflight, a new era of space exploration may be on the horizon.

In the first images released of Ultima Thule, the object looked like two spheres — kind of like a snowman. The latest photo shows a very different perspective.

Kicking a field goal seems pretty straightforward: you just kick the ball as hard as you can between the goal posts at the back of the end zone. But if it were that easy, then kickers would almost never miss. Join physicist Tim Gay and semi-pro football kicker Hermes Lima as they explain all the factors that go into kicking a successful field goal.

Stunning new archaeological evidence provides clues about the Egyptians who built the Great Pyramid of Giza--and how they did it. Join researchers as they delve into the logbook of a work crew and discover how the massive project transformed Egypt.

The Arctic is warming at a rate almost twice the global average. This could be making vortex splits more likely, but is still up for debate among climate experts.

This 12-year-old boy is legally blind, nonverbal, and has limited use of his hands. But artificial intelligence technology is helping him communicate with his family members.

In May 2018, Kīlauea volcano erupted, obliterating neighborhoods with devastating force and uprooting thousands of local residents. It is Hawaiʻi’s most destructive volcanic eruption in generations. How can one of the most beautiful places on Earth suddenly transform into a roaring inferno, sputtering molten lava and bombs of volcanic rock the size of refrigerators?

A government shutdown impacts thousands of scientists and researchers across the country. It stalls out field projects, stops weather models from being maintained, and interrupts long-term data collection vital to the health of the national parks. Some even worry it represents a threat to public safety.

Blood moon. Blue moon. Harvest moon. Supermoon. Each of these phrases refers to a distinct appearance of Earth's moon, corresponding with different lunar phases we see in the sky. So what exactly can these names, and “super blood wolf moon,” teach us?

Take a look back at some of the biggest science stories of 2018—from CRISPR gene editing to a mission to find alien worlds.

The theory of quantum mechanics presented at the meeting said that a particle like an electron isn’t physically real until it’s observed, measured by an instrument that can detect it. Before it’s detected, instead of being a solid particle, an electron is just a fuzzy wave, a wave of probability.

In seeing quantum entanglement as central to physics, The Fundamental Fysiks Group were decades ahead of their time.

NASA's New Horizons spacecraft is about to visit the most distant object ever explored by humans.

After years of anticipation, NASA scientists received the most detailed images from its spacecraft, New Horizons.

The New Horizons spacecraft made history by conducting the farthest ever flyby of an object in our solar system.

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.
