LEEDS, England, Dec. 19 (UPI) -- New X-ray images of Earth's outer core have revealed a unique jet stream-like current of molten iron. The revelatory images were captured by European Space Agency's Swarm satellites.
"We've not only seen this jet stream clearly for the first time, but we understand why it's there," Phil Livermore, a researcher at the University of Leeds, said in a news release. "We can explain it as an accelerating band of molten iron circling the North Pole, like the jet stream in the atmosphere."
