NGC925 is a barred spiral galaxy high in the nothern sky in late summer, into the winter, about 30
million light years from us. It has only a loosely-wound spiral structure, with the arm on one side being distinctly more pronounced than the arm on the other side; it is thought that this may
be the result of a collision between NGC925 and another galaxy. It has a diameter of about 95,000 light years (a good-sized galaxy, but smaller than our Milky Way).
The galaxy is tilted 55 degrees from us, so that it looks more elliptical than it is. The pink blobs strewn about the galaxy's arms are areas of intense star formation, in which hydrogen gas
has been ionized by the new, energetic stars.
The entire field of the uncropped version of the photo is about the same width as a full moon. As always, it's fun to examine the full resolution, uncropped version to find background galaxies,
hundreds of millions of light years away.
