Its loss from magma suggests that the planet has a deep reservoir of primordial helium, and the new compounds suggest that Earth’s iron-rich core could hold some of that helium. But the team ...

Where the Earth’s core meets the mantle, there are two giant regions that have baffled geologists for fifty years. A new piece of the puzzle has now emerged with the discovery that they have ...

Primordial helium from the beginning of the solar system may be stuck inside Earth's solid core, new research suggests. The findings could have implications for a long-standing debate about how ...

The mantle is the rocky envelopment that surrounds the iron core of rocky planets. The structure and dynamics of Earth's lower mantle play a major role throughout Earth's history as it dictates ...

Scientists have identified another possible commonality between Earth and Mars: a solid inner core. Scientists have identified another possible commonality between Earth and Mars: a solid inner core.

While the company behind the drive, Exodus Propulsion Technologies, says that the drive can achieve a thrust to counteract Earth’s gravity, such a claim still needs independent verification and ...

Many geologists think these ancient rocks formed above hot plumes that rose from above Earth’s molten metallic core, rather like wax in a lava lamp. Others maintain they formed by plate tectonic ...

Each up to 559 miles tall and thousands of miles wide—and together covering some 25 percent of the surface of our planet's core— Earth's LLVPs were first discovered in the 1980s, when ...

While President Trump insisted that Americans would not bear the cost, new estimates imply that the burden of tariffs could fall heavily on consumers. Tariff Gambit Bets Americans Will Swallow ...

The work was done by Haruki Takezawa and Kei Hirose at the University of Tokyo and colleagues, who suggest that Earth’s core could host a vast reservoir of primordial helium-3 – reshaping our ...
