Coronal Heating: Issues Revealed from Hinode Observations

The corona, which is observed around the Sun during total solar eclipses, has a temperature of a few million degrees. The temperature of the Sun monotonically decreases from the core to the surface that we call the photosphere, and then, the temperature rapidly increases outward by two orders of magnitude from the photosphere to the corona, which starts at a distance of a few thousand kilometers above the photosphere. In this article, I introduce the understanding that has recently been improved by observations from high-performance telescopes onboard Hinode regarding the site where coronal heating occurs.
