This pair of
Astrobin Debut Objects Is located in the constellation of Virgo at a declination of +3 degrees.
NGC 5636, at top, is the more interesting galaxy. This barred ring spiral is a magnitude 11.3 galaxy located 100 million light years away. It spans 1.3 arc-minutes in our apparent view, which corresponds to a diameter of only 40,000 light years. From our view perspective, the disk is inclined about halfway between edge-on and face-on.
The 2 arms originate at opposite ends of the long bar, extending counterclockwise for just over 180 degrees. The arms form a pseudo-ring around the bar. This galaxy is unusual in that the typical outer region of such a galaxy is almost completely absent here.
NGC 5638 is a bit closer at 90 million light years, meaning that these 2 are likely not interacting. This elliptical is slightly larger and brighter than NGC 5636. The magnitude 11.2 galaxy spans 1.9 arc-minutes in our apparent view, which corresponds to a diameter of 60,000 light years.
2 interesting edge-on spirals are also seen in the frame, UGC 9310 at left and UGC 9285 at lower right.
