I’m glad I’m not the only one who thought it looked more like a seahorse head.
I think the actual horse-head is that tiny dark cloud, about 1/2 inch long in the original picture? It took me a while to figure that out.
Yes, that’s the part that I think looks like a seahorse. See this earlier thread:
Oh, I get it now! 
BTW, I’m waiting for Denny to show up…I suspect he’ll recognize the horse I used for the bottom image… 
I was just listening to an astrophysicist on NPR discussing how the great “void” in space discovered last August is direct evidence for multiple universes. (Yeah, so like what is the “uni” for, right?).
My guess is the horsehead shape is actually the void left behind when that particular horse (or seahorse) galloped (or swam) off in search of a better life elsewhere. Or maybe it’s evidence of intergalactic rustlers or poachers? Either way, I’m too busy right now to go chasing it down.
One 'verse.
One heart.
Let’s get together and feeel alriiight.
