Mantle Plume

An asteroid the size of One World Trade Center has a very small chance of crashing into Earth in the year 2182. But what would this impact mean for life on Earth?

On a recent flyby, the Juno spacecraft spotted intense volcanic activity on Io, one of Jupiter's moons. It was more extreme than any volcanism ever seen on Io. The post Juno spots most extreme volcanic activity on Io to date first appeared on EarthSky.

A stunning composite image, made up of three years' worth of satellite photos, shows the ancient lava of Libya's Haruj volcanic field interspersed with patches of golden sand.

Tristan da Cunha is a group of islands in the South Atlantic that formed from the breakup of the supercontinent Gondwana. Today, it's home to a tiny and extremely isolated farming community.

Plate tectonics, or the recycling of Earth's crust, may have begun much earlier than previously thought—and may be a big reason that our planet harbors life

This one has planet-wide repercussions.

Beads of volcanic glass collected by Chang'e-5 are only 120 million years old.

Lava is continuing to spew from a volcano in southwestern Iceland, the sixth time since December the volcano has erupted on the Reykjanes Peninsula

"These recent Icelandic eruptions have garnered attention from Earth scientists."

To experience a volcanic eruption is to witness nature's raw power. If you would like to see one for yourself, Iceland is a great location for it. Since 2021, seven eruptions have taken place along the Reykjanes Peninsula, close to Reykjavík.

The Southern Ocean is wild and dynamic. It experiences Earth's strongest winds and largest waves. It is home to city-sized icebergs and the biggest ocean current on the globe, as well as tiny turbulent flows that fit inside a teacup.

The eruptions that began in 2021 in Iceland could last for centuries, which is bad news for Icelanders but good news for scientists seeking to understand how...

An ocean that opened up in what is now Mongolia 410 million years ago was created by a hot upwelling of rock known as a mantle plume.

Mars has a distinct structure in its mantle and crust with discernible reservoirs, and this is known thanks to meteorites that scientists at Scripps Institution of Oceanography at UC San Diego and colleagues have analyzed on Earth.

Measurements of sulphur isotopes in Io's atmosphere show that the moon may have been volcanically active for its entire lifetime

A massive column of sulfur dioxide pumped out by the erupting volcano on Iceland's Reykjanes Peninsula is traveling across northern Europe. Scientists are...

The debris from the formation of a relatively small crater on Mars created billions of additional craters, which could help us learn about Martian geology

This marked the third eruption since December 2023.

"It's just extraordinary."

A volcano on Iceland's Reykjanes Peninsula erupted for the third time in three months, sending lava 2.8 miles west from the huge fissure in Earth's surface.
