Is Earth's inner core solid or liquid? While the inner core is extremely hot, experts have known that it is solid for many ...

To understand how Earth's magnetic field has evolved over its history, geophysicists use models that simulate the thermal state of the core and mantle. These models help us understand how heat is ...

“We find that both exhibit strong linearly increasing trends, coupled with a large surge in magnitude between 330 and 220 ...

Earth’s inner core is a hot, solid ball—about 20% of Earth’s radius—made of an iron alloy. The planet’s outer core, beneath the rocky mantle, is a colder, liquid metal. Geophysics models explain that, ...

Today will be the shortest day of your life. Our lives, too. Everybody's lives. According to those who keep up with atomic ...

The strength of Earth’s magnetic field and the amount of oxygen in its atmosphere seem to be correlated—and scientists want to know why ...

Earth’s magnetic north is not static. Like an anchorless buoy pushed by ocean waves, the magnetic field is constantly on the move as liquid iron sloshes around in the planet’s outer core.

Earth’s magnetic field has correlated with fluctuations in atmospheric oxygen, according to a newly released study.

A ‘ghost plume’ identified deep in the mantle beneath Oman suggests there may be more heat flowing out of Earth’s core than previously thought ...
