WASHINGTON (Reuters) - Scientists using an ocean drilling vessel have dug the deepest hole ever in rock from Earth's mantle - penetrating 4,160 feet (1,268 meters) below the Atlantic seabed - and ...

Earth’s inner core has both changed its relative rotation rate and deformed in the past few decades, according to an analysis of seismic waves recorded when the inner core occupied the same relative ...

Previous analyses of seismic activity on Mars suggested its core was surprisingly large, with a low density. Two new studies suggest the opposite. NASA, ESA and Z. Levay (STScI) The Red Planet’s core ...

To understand the mantle—the largest layer of Earth’s rocky body—scientists drill deep cores out of the Earth. Scientists drilled the deepest core yet and recovered serpentinized peridotite that forms ...

Approximately 3,000 kilometres beneath the Earth’s crust lies the scorching, dynamic core—once thought to be sealed off from the rest of the planet. However, new research challenges this long-standing ...

About 4.5 billion years ago, a Mars-sized object smashed into the young Earth, spraying debris that coalesced to form the moon, many scientists think. Some remnants of that object, called Theia, exist ...

The mantle has three to five times more carbon than researchers would expect based on the proportion of elements in stars and other planets. The diamonds found in this layer of Earth might explain the ...

Researchers at Göttingen University have uncovered new evidence that some of Earth’s most precious metals began their journey far deeper than once thought. Working with volcanic rocks from ocean ...

For the first time, scientists have directly measured the amount of heat flowing from the molten metal of Earth’s core into a region at the base of the mantle, a process that helps drive both the ...

The Earth’s inner core, a solid sphere predominantly composed of iron and nickel, occupies a central role in our planet’s evolution and geodynamo processes. Although hidden beneath thousands of ...
