Wow. In my memory, it was the pressure from the hot gases that kept a star from collapsing on itself. I did not know it was light pressure! Is this a typo in the article, or is it really light pressure holding up stars?

More specifically radiation pressure, not all of it is visible light. Some quick searching turns up http://en.wikipedia.org/wiki/Radiation_pressure#Stellar_inte... and http://www.astro.caltech.edu/~george/ay20/Ay20-Lec7x.pdf

And, from the wikipedia article:

"In the Sun, radiation pressure is still quite small when compared to the gas pressure. In the heaviest non-degenerate stars, radiation pressure is the dominant pressure component"
