The presence of Corona:

So when we look back over the centuries we see that doctrines of the interpretation of nature, which were held as sound and good for their time, fell from honor when faced with the light of some new scientific theory.

 

Back to Evidence for a Liquid Photosphere

It is without question that the solar corona it indeed a gaseous plasma.  Note that it has all the characteristics of a true sparse state (no surface, no continuous spectrum, not subject to seismological studies, unable to boil).  It is proper to think of the corona as representing the "vapor" surrounding the denser and condensed photosphere.  This is typical of every liquid-gas equilibrium observed on earth.  The corona has no distinct boundary.  It is the true gaseous plasma, not the photosphere.
