Smiley Face Galaxy.

This is a picture of the central region of a group of galaxies 300 million light-year away called Stephan's Quintet, taken by the Spitzer space telescope and a ground-based telescope in Spain.

The distant galaxy is generating a 'sonic boom' of cosmic proportions, astronomers have discovered, as one of the galaxies falls towards the others at high speed, ploughing through a cloud of hydrogen gas travelling at 540.6 miles per second - 100 times faster than the speed of sound.

That's all fine and dandy - but this is the interesting part: can you find the smiley face in the picture? (That's Petunia smiling, I think) Link
