It's only true that "limb brightening" is not a term with it's own article in Wikipedia yet, which is unfortunate. Limb brightening is less common than darkening, but is a very real effect with known causes. My copy of the textbook Introductory Astonomy & Astrophysics has listings in its index for both terms.
I had never heard of this, especially not in relation to the sun though I could imagine it or some similar term being used to describe the way the atmosphere of some planets behaves. I now see it is used but I still don't think that the description is wrong, even if it is confusing. Alan's explanation is also helpful for clearing this up.
Agreed. Shalom oh mighty geck. :wink:
Just as zero is not equal to infinity, everything coming from nothing is illogical.

The "above image" link (currently at least) brings up a different image to the APOD and is dated "November 6, 2011". :?

General question.
How many functioning suns could our sun be divided into?

Engineer's answer: Depends on the price. :ssmile:

Edit: in theory, maybe into 12 or 13 red dwarf stars.
