   How deep is the Sun's magnetic field?

   • The group’s calculations showed that magnetic fields can be generated about 20,000 miles (32,100 kilometers) below the sun’s surface — far closer to the surface than had previously been assumed. Other models had suggested it was much deeper — around 130,000 miles (209,200 kilometers).

   Does the Sun have a magnetic field?

   • “The features we see when looking at the sun, like the corona that many people saw during the recent solar eclipse, sunspots, and solar flares, are all associated with the sun’s magnetic field,” says study author Keaton Burns, a research scientist in MIT’s Department of Mathematics.

   Is the Sun's magnetic field shaped by a shallower process?

   • But an MIT study finds that the sun's activity may be shaped by a much shallower process. In a paper appearing in Nature, researchers at MIT, the University of Edinburgh, and elsewhere find that the sun's magnetic field could arise from instabilities within the sun's outermost layers.

   Could solar flares and sunspots be caused by a magnetic field?

   • Surprise findings suggest sunspots and solar flares could be generated by a magnetic field within the Sun’s outermost layers. If confirmed, the findings could help scientists better predict space weather. This illustration lays a depiction of the sun's magnetic fields over an image captured by NASA’s Solar Dynamics Observatory on March 12, 2016.

   How does a star move through a magnetic field?

   • The flow of plasma within the sun creates the star’s magnetic field. This means the sun has two magnetic poles, like the Earth—but every 11 years, these poles flip positions. As the star goes through this cycle, it gradually shifts between periods of low and high activity.

    May 22, 2024 · Since first observing the sun’s magnetic activity, astronomers have struggled to pinpoint where the process originates. Now, after running a series of complex calculations on a NASA supercomputer, the researchers discovered the magnetic field is generated about 20,000 miles below the sun’s surface.
