Scientists Discover A Jet Stream Within Earth’s Iron Core Through X-Ray View Of The Planet
Earth’s molten iron core
Using the latest satellite data that helps create an 'x-ray' view of the planet, scientists discovered a jet stream within the Earth's molten iron core. Lead researcher Phil Livermore from the University of Leeds in Britain said,
Because of the core's remote location under 3,000km of rock, for many years scientists have studied the Earth's core by measuring the planet's magnetic field - one of the few options available.
Previous research had found that changes in the magnetic field indicated that iron in the outer core was moving faster in the northern hemisphere, mostly under Alaska and Siberia. But new data from the Swarm satellites revealed these changes are actually caused by a jet stream moving at more than 40km per year. This is three times faster than typical outer core speeds and hundreds of thousands of times faster than the speed at which the Earth's tectonic plates move.
The European Space Agency's Swarm mission features a trio of satellites which simultaneously measure and untangle the different magnetic signals which stem from the Earth's core, mantle, crust, oceans, ionosphere and magnetosphere. They have provided the clearest information yet about the magnetic field created in the core, according to the scientists.

Introducing ElectionsHQ + 50 Ground Reports Project
The 2024 elections might seem easy to guess, but there are some important questions that shouldn't be missed.
Do freebies still sway voters? Do people prioritise infrastructure when voting? How will Punjab vote?
The answers to these questions provide great insights into where we, as a country, are headed in the years to come.
Swarajya is starting a project with an aim to do 50 solid ground stories and a smart commentary service on WhatsApp, a one-of-a-kind. We'd love your support during this election season.
