[Full version of image]
[The Pinwheel Galaxy] is a beautiful face-on spiral galaxy that is some [25 million light-years] with a measured size that is about twice as large as our own Galaxy. You can’t really tell in my photo above but in much more detailed photos (e.g. [this one by the Hubble Space telescope]) you can see that M101 appears to be asymmetrical. It is believed that this was due to a tidal interaction with another galaxy as it passed by.
