Not only does this research offer new clues about how Earth has maintained the delicate balance needed for life, but it may also help scientists identify the conditions necessary for habitability on ...

Earth’s core could contain helium from the early solar system. The noble gas tucks into gaps in iron crystals under high pressure and temperature.

USC scientists have made a groundbreaking discovery about the nature of Earth’s enigmatic inner core, revealing for the first time that this 1,500-mile-wide ball of iron and nickel is changing.

As the Earth gradually cools, the inner core expands outwards at the surrounding iron-rich liquid “freezes”. That said, it is still extremely hot, at least 5,000 Kelvin (K) (4726.85°C).

The latest discoveries about the inner core have fueled vigorous disagreements among the world’s top Earth scientists, USC’s John Vidale says. Some don’t believe the core turns at all.

Earth Earth’s core is oddly squishy and we may now know why Earth’s iron-rich inner core may owe some of its surprising softness to the motion of atoms, suggest experiments with iron at high ...

Earth's inner core is a solid ball of mostly iron and nickel. Measuring about 1,520 miles (2,440 kilometers), this inner core spins inside the outer core, an ocean of molten iron and nickel about ...
