It's a crab!
Why a crab emoticon, you ask? Well...
Earlier today Joules showed me this lovely pic of a nebula from the Astronomy Picture of the Day site. I remarked that I could see a crab in the image, while Joules said she saw an Anglerfish.
All very interesting. Anyway, 'Crab Nebula' was ringing dim bells so I googled it, as you do, and found this on Wiki. We both thought - Joules and I - that that looked less like a crab than mine!
So yes, a crab emoticon was forthcoming from me.
What? You want logic? Pffft... :)
