The suns surface is a brilliant display of sunspots and flares driven by the solar magnetic field, which is internally generated through a process called dynamo action. Astrophysicists have assumed that the suns field is generated deep within the star. But an MIT study finds that the suns activity may be shaped by a much shallower process.

The solar dynamo that drives sunspots and solar flares could be located near the surface of the sun scientists find, solving a 400-year-old solar mystery and providing a weird link to black holes.

Magnetorotational instability—a process that might explain the dynamics of astrophysical accretion disks—has finally been observed in the laboratory.
