“’MRI’ of the Sun’s interior motions challenges existing explanations for sunspots”

A team of scientists has created an “MRI” of the Sun’s interior plasma motions, shedding light on how it transfers heat from its deep interior to its surface. In order to develop their “MRI” of the Sun’s plasma flows, the researchers examined high-resolution images of the Sun’s surface, shown above, taken by the Helioseismic and Magnetic Imager (HMI) onboard NASA’s Solar Dynamics Observatory. Using a 16-million pixel camera, HMI measures motions on the Sun’s surface caused by convection. PHOTO: NASA
“A team of scientists has created an “MRI” of the Sun’s interior plasma motions, shedding light on how it transfers heat from its deep interior to its surface. The result, which appears in the journal the Proceedings of the National Academy of Sciences, upends our understanding of how heat is transported outwards by the Sun and challenges existing explanations of the formation of sunspots and magnetic field generation.”
If nothing else, this article shows that we don’t know what we think we know about the workings of the sun.
