A new study reveals how shifting ice shells on icy moons can cause dramatic pressure changes, sometimes enough to boil their hidden oceans. The outer planets of our Solar System are accompanied by ...

A groundbreaking study, recently published in Geology, has uncovered the vital role of carbon dioxide in the journey of diamonds from deep within the Earth’s mantle to the surface. The research, led ...

Zealandia, considered a candidate for the Earth’s eighth continent, was mostly lost to the sea. Geologists say they’ve now ...

A deep heat mass beneath the Appalachians appears to have started near a rift between Greenland and North America. Its slow southward journey reveals that ancient tectonic events still influence the ...

Atoms found deep inside our planet argue that parts of “proto-Earth,” the early version of our planet, still survive inside the mantle.

At 900 meters, the giant crater in southern China is three times larger than the previous Holocene recorder holder.

(THE CONVERSATION) When astronomers search for planets that could host liquid water on their surface, they start by looking at a star’s habitable zone. Water is a key ingredient for life, and on a ...

A ridiculous but instructive thought experiment involving deep time, plate tectonics, erosion and the slow death of the sun ...

Scientists have long wondered why Earth's overall makeup doesn't fully match the mix of materials found in ancient meteorites. One hypothesis has been that our proto-Earth (what the earliest stages of ...

If our planet flips and no one’s around to hear it, does it still make a sound? Scientists have managed to put a chilling soundtrack to the flipping of Earth’s magnetic field — and the result is ...

A pair of diamonds that formed hundreds of kilometers deep in Earth’s malleable mantle both contain specks of materials that form in completely opposing chemical environments—a combination so unusual ...

the Earth you walk on today might not be the same planet that was born 4.5 billion years ago. Many scientists believe that in its infancy, Earth collided with another world the size of Mars, and that ...
