Answer 2

A corona (pl. coronas or coronae) is the outermost layer of a star's atmosphere. They are made up of plasma.

The Sun's corona lies above the chromosphere and extends millions of kilometres into outer space. It is most easily seen during a total solar eclipse, but it is also observable with a coronagraph. Spectroscopic measurements indicate strong ionization in the corona and a plasma temperature in excess of 1000000 kelvin,[1] much hotter than the surface of the Sun, known as the photosphere.

The word "corona" is Latin for 'crown', in turn derived from Ancient Greek κορώνη, korṓnē, 'garland, wreath'.
