Objects that are hotter are brighter. Which bulb is hotter? Which
is hotter, the sun’s surface or a sunspot? How do you know?
But, what causes sunspots?
The sun rotates faster at its equator than at its poles. The sun’s
strong magnetic field gets wound up causing part of the fields to rupture the surface where they cause sunspots.
Fast-moving charged particles are deflected by magnetic fields.
The magnetic fields of sunspots deflect hotter gases allowing
only cooler gases that experience less of this deflective force.
