Mysteries of the Sun

The Sun’s surface is blisteringly hot, sweltering at temperatures that hit over 10,000 degrees Fahrenheit, but its atmosphere is even hotter. Our current understanding is that the further you move away from a source, the cooler the environment gets, however, with the Sun, this is not the case.
Why does it unpredictably spew out torrents of energised particles?
These particles impact the Solar System, in particular, the Earth’s magnetosphere, which creates the aurora. It also presents a hazard to spacecraft and astronauts, and can trigger storms that have been known to disable satellites and knock out terrestrial electric power grids for periods of time.
