Over the years scientists have discovered many things, but none like this. This time they have discovered a magnetic field on the surface of the sun. The magnetic field arches loop from the surface of the sun to the corona, which is the upper atmosphere. The loops get hotter with height. We are able to see the loops because bright surface plasma flows along the curves.
