A new study of decades worth of seismogram data shows that the surface of Earth’s iron and nickel core is more malleable than scientists thought.

For a long time, scientists thought the Earth's inner core was a solid ball of metal, sort of like a planet within a planet that sits some 3,000 miles (4,828 kilometers) below the surface.

Deep within Earth’s mantle lie two enormous, continent-sized structures known as LLVPs. Scientists once believed these ...

Earth appears to be a chill blue planet, but deep down, it’s really a metalhead. Its outer core is mostly molten iron (and ...

"We were quite surprised," Dones continued. "Spirals are seen in Saturn's rings, disks around young stars and galaxies. The ...

Scientists confirm the Moon has a solid iron core, like Earth’s, with a molten outer layer. This discovery reshapes our ...

Well, from the aforementioned observations, it has been possible to determine that the Earth's inner core has temperatures ... may indicate a change in the structure of iron, suggesting perhaps ...

The resulting composition now covers up to 30 percent of the core, slowing the seismic waves geologists use to probe Earth's ...

The Earth's inner core, long considered a solid and stable sphere ... The analysis of seismic waves allows us to deduce its structure and composition. As these waves pass through different layers, ...

Could a giant planet between Mars and Jupiter have doomed Earth? A new study suggests that small changes would have been ...

though we only ever see the ones that show up in the inner solar system as long-period comets. Estimating the cloud's structure requires more than understanding the planet's gravitational forces.
