APOD: Orange Sun Sparking (2014 May 06)

[BDanielMayfield]

Limb darkening is an actual term. Limb brightening is not.

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.

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

Should'a left off "above" in the link.

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

Engineer's answer: Depends on the price.

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