Necklace Nebula (2013)

The necklace nebula is weird. Sure, it glows in all the usual colors, but the little red bits are arranged perfectly in a circle around the central stars (visible as a single star) and then there are the two other red bits at considerable distance from the rest of the nebula at the upper left and lower right. I brightened those distant ones a little to make them easier to see. To understand these baffling features, I recommend reading this article because the authors definitely know more than I do.
