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 ...
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 ...
