Southern Pinwheel Galaxy: M83 in this face-on view is a huge spiral galaxy, about 12 to15 million light years distant, and belongs like NGC 4945 and Centaurus A to a group of galaxies. It has all the features of a relatively young spiral galaxy: Star forming regions can be observed as blue and pink knots in the spiral arms. Also the huge dust bands indicate that there is a lot of genesis going on in this star island. Milky Way would probably look quite similar from a distance of millions of light years.
Also  notice the two galaxies at the bottom, which are much more distant.

An image of the center of M83 with one of the ESO 8.2 meter telescopes at Cerro Paranal in Chile you can see here.
A comparison of the two images you will find here.

The image was taken at the IAS astronomical site at the Hakos farm in Namibia.
