Stunning new ESA animation reveals the Earth's magnetic 'cocoon' in unprecedented detail

Animation reveals a detailed look at Earth's ‘lithospheric magnetic field’

The layer makes up 6 percent of the magnetic field, and is hard to see from space

ESA's Swarm satellites collected data for three years for high resolution view

암석권 자기장은 지구를 둘러싸고 있는 거대한 보호막에 있는 약한 층으로 

자기장의 6%를 차지하고 있으며 우주에서는 보기 힘들다.

The European Space Agency has released the highest resolution map yet of Earth’s elusive ‘lithospheric magnetic field,’ a weak layer in the massive ‘cocoon’ around our planet.

The agency’s Swarm satellites have mapped the magnetic signals of this layer in unprecedented detail, revealing new insight to Earth’s magnetic history.

A stunning new animation created after three years of data collection now shows the finer details of this small section, which arises from the electrical currents in space and the magnetized rocks of our planet’s upper lithosphere.

LITHOSPHERIC FIELDS

The ‘lithospheric magnetic field,’ is a weak layer in the massive ‘cocoon’ around our planet. 

The planet's molten iron core generates the majority of the magnetic field, according to ESA. 

The remaining 6 percent is created, in part, by electrical currents in space that surround Earth, as well as by magnetized rocks in the upper lithosphere, an area encompassing Earth's crust and upper mantle. 

 

While much of Earth’s magnetic field is generated by deep movement of molten iron in the outer core, at depths of more than 3000 kilometers (1865 miles), a much weaker layer making up just 6 percent comes from the crust and upper mantle.

While it’s hard to spot from space, the Swarm satellites have allowed scientists to map the lithospheric magnetic field in stunning detail.

This reveals more precise variations than previous reconstructions, as a result of geological structures in Earth’s crust.

‘By combining Swarm measurements with historical data from the German CHAMP satellite, and using a new modelling technique, it was possible to extract the tiny magnetic signals of crustal magnetization,’ said Nils Olsen from the Technical University of Denmark.
