This one is inside a larger, fainter structure that simply doesn’t show up as far as I can tell in the Hubble data. Even if it is there, it’s cut off a bit in this view. Have a look at this image to see what I mean. The way the fainter shell tapers at one end is strange.
North is NOT up.
Hubble data is public domain, but I put a lot of work into combining it into beautiful color images. The minimal credit line should read: NASA / ESA / J. Schmidt
