[edit] Ambiguous sentence

From the article:

The image reveals two 'caps' of less ionised material at the edge of the nebula

Should it be read as that the material in these regions are less ionised compared to other regions; or that the concentration of ionised particles is lower, or something else?

If it is singly ionized nitrogen; does it have to be mentioned at all? In such case it is already mentioned in the text that green represents singly ionized nitrogen. Gunnar Larsson 19:03, 14 September 2006 (UTC)

[edit] Images

Why have they suddenly all disappeared? Several beautiful NASA public domain images have been deleted for no apparent reason.

The question has been here for a month, and no explanation offered.... were they just deleted for fun, then? 81.179.65.38 00:22, 23 December 2006 (UTC)
