Given the depth of this particular image, it's hard to tell whether it's a dwarf/satellite of NGC 1309 considered part of the galaxy's structure or an irregular object in the background. Galaxies do indeed rotate, just very slowly from our perspective. As an example, our Sun completes one revolution around the Milky Way roughly once every 250,000,000 years.

I have looked at the largest image, but can't work it out. Do galaxies spin? Is this the result of some kind of 'turbulence'?
