A typical temperature for the quiet solar corona is ~ 1.5 x 106K, whereas the photosphere – the likely source of the thermal energy – has a temperature less than 6 × 103 K. Although many theories have been advanced to explain why the corona is so much hotter than the photosphere, this old problem remains unsolved. However, there is a mechanism based on

In the past decade what is known about the corona has been vastly enlarged by instruments on the ground and on spacecraft, manned and unmanned. The corona is observed to be in a continuous state of flux, punctuated by periodic explosive outbursts. From spectroscopic observations the temperature of the corona is estimated to be between one and two ...

This paper reviews our present understanding of coronal heating, structuring and variability that has emerged from space observations of the Sun and nearby stars. It is shown that a basic analogy exists between solar coronal physics and the phenomena observed in the coronae of other late-type stars.
