mages of the Sun showed that its outer layer is filled with almost unexplored, very thin magnetic filaments, consisting of plasma heated to several million degrees. All previous images of the Sun did not allow scientists to understand what this upper layer of the star consists of.
The width of one plasma filament is about 500 km. The exact physical mechanism that allows such threads to be created is still unknown.
The following high-resolution images of the Sun will be made by the Parker Solar Probe probe and ESA (SolO) solar orbiter.
