The liquid iron in Earth's outer core doesn't always behave as expected. When it changed direction in an unexplained way, ESA satellites provided data on the direction of flow, helping scientists gain ...

Figure 2: Map of annual difference of the second time derivative of the vertical component for epoch 2003.5. High-resolution core magnetic-field models like xCHAOS make it possible to investigate core ...

Some metals are in liquid form, the prime example being mercury. But there are also enormous quantities of liquid metal in the Earth's core, where temperatures are so high that part of the iron is ...

Add Yahoo as a preferred source to see more of our stories on Google. A recent study has revealed an unexpected shift that happened beneath the Pacific Ocean in 2010. Using decades of satellite and ...

Earth’s magnetic field is thought to be generated largely by an ocean of superheated, swirling liquid iron that makes up Earth’s outer core 3000 km under our feet. Credit: ESA/AOES Medialab The ...

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 ...
