These holes emit high-speed particles from the sun like water from a shower head.
The Parker Solar probe observed narrow plasma structures as it got close to around eight million kilometers of the sun's surface. These streams appear to be controlled by magnetic fields that trace back to the sun's cold spots known as coronal holes.
According to the release, as magnetic fields pass each other in opposing directions within these solar surface funnels, they break and reconnect, thereby sending“The big conclusion is that its magnetic reconnection within these funnel structures that are providing the energy source of the fast solar wind,” Stuart D. Bale, a professor of physics at the University of California, Berkeley, said in a statement.
Which means, the probe observed highly energetic particles traveling at a speed about 10 to 100 times faster than the solar wind, implying that the fast wind is caused by magnetic field reconnection blasted out from these holes.
