Scientists Discovers Molten ‘Jet Stream’ Deep Inside Earth

Scientists Discovers Molten ‘Jet Stream’ Deep Inside Earth According to a new study, published in the journal Nature Geoscience, scientists for the first time have discovered a huge jet stream of molten iron deep within the Earth’s core, around 1,860 miles (3,000km) below the surface.Researchers believe the jet is likely to be caused by liquid in the core moving towards a boundary from both sides, causing it to be

squeezed out sideways. The discovery could shed light on how Earth protective, magnetic shield works. According to scientists, the stream is moving at about 40km per year and is roughly 420km wide. This speed is three times faster than normal outer-core speeds and hundreds of thousands of times faster than rate at which Earth’s tectonic plates move. The discovery was made by the researchers from the University of Leeds, using the European Space Agency (ESA’s) trio satellite known as Swarm satellites which map the Earth’s magnetic field to better understand its workings. The three satellites were launched in 2013 with the goal of studying Earth’s magnetic field. The European Space Agency’s Swarm satellites are providing sharpest X-ray image yet of the core.
