DTU researchers find river of molten iron in the Earth’s core

Deep down in the Earth’s core a massive river of molten iron is moving westward under Alaska and Siberia at increasing speed. The remarkable movement have been detected with very precise data from the European Swarm satellites.

Earth’s magnetic field under the ‘simulation magnifying glass’

Earth’s magnetic field has reversed direction hundreds of times in the course of our planet’s history. But the cause of those reversals remains unclear. 4 million CPU hours of simulations on the ‘Piz Daint’ supercomputer at CSCS offer fresh clues that point to a phenomenon called ‘dynamo waves’ playing...

New theory about the weakening of the Earth’s magnetic field

The Earth’s magnetic field, which protects the planet and its 1,300 satellites against particles from outer space, is becoming weaker and weaker. A DTU researcher may have pinpointed the reason why.

First Swarm results make front page news

The three Swarm satellites have made the front page of the renowned international journal "Geophysical Research Letters", thanks to the first mathematical model of the Earth's magnetic field, based on the high-resolution magnetic measurements made by the satellites. Nils Olsen from DTU Space heads the international team that has calculated...

New knowledge about Earth’s magical magnetic field

A DTU researcher and his French colleagues are one step closer to explaining what is going on deep inside the Earth. In a recently published article in Nature, they explain how the Earth’s magnetic field is formed and describe how it impacts the surface.
