Description

This Astrobin Debut Object is a pair of uniquely structured spiral galaxies located in the constellation of Pegasus at a declination of +26 degrees.    Although they appear to be close together in this image, they are 60 million light years apart (one much behind the other) and therefore are not interacting.  But even though they are not interacting with each other, they each appear to be interacting with something else because of their extended star streams and disturbed disks.

NGC 23, at upper right, is a magnitude 12 galaxy which is located 170 million light years away. It spans 2.7 arc-minutes in our apparent view, which corresponds to a Milky Way size diameter of 120,000 light years.  I love the bright core of this galaxy, as well as the interesting arm structure.

NGC 26, at lower left, is a magnitude 13 galaxy which is located 230 million light years away.  Not counting the star stream extending to the left, the main disk spans 1.4 arc-minutes in our apparent view.  This corresponds to a diameter of 95,000 light years.   It is fascinating to me how the outer disk seems to disappear in the upper and lower regions.
