I think mine has to be http://apod.nasa.gov/apod/ap111024.html - the Waterfall Nebula. There's so much going on here! Start at the "top" of the enigmatic namesake- there's even a faint arch of dust that resembles the mouth of a cave from which the river flows. Then, as it cascades off the side of the cliff, funneled by the peaks and valleys of the cliff, you can see what appears to be its shadow cast onto the dust wall behind it by a neighboring star. You follow the fall down to its "base" and to the brilliant (and almost unobscured) birth of a star, with its plasma jet and shock wave blasting toward the bottom of the frame. You follow the jet up toward its source, encountering a small bright spot that could be the star, but there are also what looks like two smaller waves coming out at 90° to the first, their trailing ends almost touching to form a disk. Maybe the bright spot is just the second burst interacting with the first? You can envision what it looks like behind that teasingly small cloud of dust as your eyes continue upward along the path of the bottom jet to dimmer wave signifying the end of its cosmic counterpart. Then, to top it off, you catch the couple dots above the upper wave that kind of lead you to a translucent egg drifting through space.
