A few months after spotting a jet stream of molten iron in the Earth's outer core, the European Space Agency's (ESA) Swarm satellites have found a similar system at work in the upper atmosphere. There, the electrical fields created through solar winds interacting with the planet's magnetic field have been found to drive supersonic plasma jets, which can heat the ionosphere to temperatures as high as 10,000º C (18,032º F).
