Our planet's gassy atmosphere does a good job of promoting life and protecting us from the odd smallish asteroid. But without the Earth's magnetic field, the solar wind — a constant gale of ...

On a time scale of tens to hundreds of millions of years, the geomagnetic field may be influenced by currents in the mantle. The frequent polarity reversals of Earth's magnetic field can also be ...

Geophysicists from ETH Zurich and SUSTech, China, have demonstrated the dynamo effect of the Earth’s core in a model in which viscosity has no influence, as is the correct physical regime for the ...

Physicists in the US have performed a simple table-top experiment that could provide new insight into why the Earth’s continents drift apart and then move back together over several hundred-million ...

We live on the most comfortable of planets. It may not be too visible, but the Earth's magnetic field plays a critical role in maintaining that comfort. The remaining rocky planets in our Solar System ...
