There are still several secrets about the Solar corona that astronomers must unveil. The corona is the uppermost solar atmosphere, made by low-density gas with temperatures as high as a few million degrees (as a comparison, the plasma in photosphere and chromosphere is at about 5600 K and 10000 K, respectively). The energy required to heat the gas up to

Nanoflares and the heating of solar corona. The study: “Statistical Signatures of Nanoflare Activity. I. Monte Carlo Simulations and Parameter-space Exploration” of D. B. Jess (Queen’s University Belfast) recently appeared on ApJ.

There are still secrets of our Sun that the scientific community struggles to unveil. One of this is the mechanism responsible for the heating of solar corona. While the photospheric plasma has a typical temperature of about 5700 degrees, in fact, the plasma in the solar chromosphere and corona is hotter: about 10000 degrees in the chromosphere and 1-2 millions
