046 - Proof of Black (w)Holes

Day 46. At the supermarket today I spotted this jar of whole black olives and was struck by the idea of the obvious visual pun. So a quick photo in the store with my Nexus, a search through Flickr to find this Creative Commons background image of the Crescent Nebula by Paul Hutchinson, and some fiddling around in Adobe Photoshop, and I ended up with this image... conclusive proof that there are black (w)holes in space.

Of course, I mean that in a relatively general sense.
