The sun s 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 sun s field is generated deep within the star. But an MIT study finds that the sun s 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.
The origin of the sun's magnetic field could lie close to its surface | MIT News | Massachusetts Institute of Technology mit.edu - get the latest breaking news, showbiz & celebrity photos, sport news & rumours, viral videos and top stories from mit.edu Daily Mail and Mail on Sunday newspapers.
