A dramatic shift in Earth’s magnetic field occurred roughly 41,000 years ago during what scientists now call the Laschamps ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects ...

As the iron and nickel inside our planet shift, so does Earth's magnetic field, meaning the North (and South) Poles are also ...

A new model uncovers how Earth’s liquid core has sustained its magnetic field since the planet’s beginnings, offering new insights into its future. Earth benefits from the presence of a magnetic field ...

The iron-rich core at the centre of our planet has been a crucial part of Earth’s evolution. The core not only powers the ...

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 ...

Scientists found that carbon enabled Earth’s core to solidify. Without it, the inner core may not exist. A team of scientists ...

Earth’s solid inner core appears to have changed shape in the past 20 years or so, according to seismic wave measurements – but the behaviour of these waves could also be explained by other shifts at ...

Earth's inner core is solid and blistering hot. For decades, scientists have known the inner core is solid thanks to the pioneering work of Danish seismologist Inge Lehmann, who first proposed its ...
