New research led by a York University professor sheds light on the earliest days of Earth's formation and potentially calls ...

New research is reshaping how scientists understand the earliest days of Earth’s formation—suggesting that the deep interior ...

After decades of debate, scientists confirm the moon has a solid iron core—mirroring Earth’s inner structure and reshaping how we understand our nearest neighbor. New data and advanced ...

Abstract: Although it is known that the geodynamo has been operating for at least 3.2 Ga, it remains difficult to infer the intensity, dipolarity and stability (occurrence of reversals) of the ...

The 2025 Arthur Holmes Medal & Honorary Membership is awarded to Paul Tackley for important advances in modelling mantle dynamics that have resulted in a deeper understanding of mantle convection, ...

Abstract: The predominant force balance in rapidly rotating planetary cores is between Coriolis, pressure, buoyancy and Lorentz forces. This magnetostrophic balance leads to a Taylor state where the ...

It’s not much of a stretch to say that Earth’s inner structure, especially the innermost spherical core, has stupefied ...

We all know that the Earth is in constant motion - it is something we learnt in school, and while we might not feel it at all, our planet is constantly moving, completing one rotation around the ...

Where the Earth’s core meets the mantle, there are two giant regions that have baffled geologists for fifty years. A new piece of the puzzle has now emerged with the discovery that they have ...

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long-standing debate over how our planet formed. Primordial helium from the ...
