England’s famed White Cliffs of Dover were formed almost 100 million years ago out of the crushed shells of tiny single-celled algae. Now a team of scientists has identified the specific ocean conditions necessary for these sea creatures to thrive.
For the first time, researchers have peered thousands of meters beneath Greenland’s glistening surface to map the bottom of the ice sheet. They were surprised to learn that it’s thawing all over the place.
NASA has spotted something strange and beautiful in the sands of Mars—a remarkable dune field that looks eerily similar to Morse code. And it has a message for us.
British geophysicists have discovered evidence of an ancient drainage network buried beneath Greenland’s ice sheet that once extended across nearly a fifth of its total surface. Some of the channels within this system were about a mile deep and over seven miles wide.
We know about our North and South poles, but what about an East, West, or slightly-to-the-left pole? According to new research published in Geophysical Research Letters, around 1 billion years ago, that might have been a possibility.
Beneath the hum of ship traffic and the chatter of marine life, another sound is emanating from the Caribbean Sea. It’s far too low pitched for humans to hear, but its signature can be detected from space. Scientists have never seen—or heard—anything like it.
For the first time, geologists have compiled a global map of the wave-like motions called “convective currents” inside Earth’s mantle. They found that those convective currents are moving roughly ten times faster than previously thought. The discovery can help explain everything from how Earth’s surface changes over…
If you’ve had your fill of depressing predictions for the future, here’s one that is both fascinating and as innocuous as they come: as ice caps melt, Earth’s rotation is slowing down, and that’s making our days ever so slightly longer.
It took 2,500 seismometers, 23 explosive blasts, and countless earthquakes, but researchers now have a much better idea of what the magma chambers look like deep below Mount Saint Helens. The weird bit? It looks like it shares a magma chamber with a whole field of local volcanoes.
What lurks beneath the dusty red surface of Mars? NASA’s InSight Lander is launching next spring to go delving deeper than ever before as the first Martian geophysicist.
Earthquakes can create copycat events up to 1,000 kiometers away — and it could be the result of the vibration of small particles, according to new computer simulations of seismic activity in the Earth.
It’s often said that we know less about Earth’s deep interior than we do about the surface of Mars (or at this point, maybe even Pluto). A new global map of subatomic particles called antineutrinos is helping to change that. It’s showing scientists just how radioactive our little Blue Marble is.
The explosions that devastated Tianjin yesterday were so powerful, they registered as seismic activity by China’s National Earthquake Network. And the “quakes” geophysicists saw don’t even begin to capture the magnitude of the blasts.
Pluto and Charon have captured our hearts and imaginations. But how did these adorably strange worlds form, and what consequences could that have on what we see now? Researcher Amy Barr Mlinar chatted with us about catastrophic collisions, subsurface oceans, and Pluto’s lack of craters.
In 1982, the ground beneath the historic port city of Pozzuoli began to rise like a cake in the oven. Within two years, the swell had exceeded 6 feet. Then the earth started shaking—first, a swarm of microquakes. When the first magnitude 4 quake hit, Pozzuoli became a ghost town overnight.
On April 22, 2015, a stratovolcano in southern Chile called Calbuco erupted for the first time in 42 years. Filmmaker Martin Heck was in the area shooting a neighboring volcano, when Calbuco came alive. He fixed his cameras on its undulating plumes of ash. This gobstopping time-lapse is the fruit of the images he…
Standing on the surface of Venus, your body would be crushed by the immense pressure, fried by the lead-melting heat, and dissolved by sulfuric acid thunderstorms. Too bad, because if you could survive on Venus, you might witness some epic volcanic eruptions.
Geophysicists have discovered a second, even more massive magma reservoir feeding the Yellowstone supervolcano, providing researchers with the most comprehensive picture yet of the volcanic system beneath the park.
Your typical thunderstorm strikes in summer, when the atmosphere is full of warm, moist air. So when lightning strikes in the middle of a winter blizzard, there is something strange going on. Thundersnow involves an entirely different type of lightning, and our skyscrapers are a key part of it.
From a satellite, the plumes venting from two volcanoes in the Democratic Republic of the Congo look like clouds. Right now, they're just spewing harmless steam and gas. But that could change.
