Friday Galactic Blogging

I make no apologies for finding pictures of spiral galaxies incredibly beautiful. The subject of this photo is NGC 7331, which at 40 million light years, is relatively nearby. Large spirals like this are often compared to the Milky Way, and this one particularly; but, with apparently at least three spiral arms (the Milky Way seems to have two) and lacking (at least to my eyes) a strong central bar, I think that's a bit of an exaggeration. Click the image for the APOD page, click through there for a high resolution version of the image.
