Description

This object is a pair of spiral galaxies located 150 million light years away in the constellation of Draco at a declination of +61 degrees. I could not find anything written on this fascinating pair of objects.

NGC 6306 is a 13.7 magnitude edge-on galaxy is that spans 1 arc-minutes in our apparent view, which corresponds to an actual diameter of 50,000 light years. The designations I have seen assume that this is one galaxy. The core of this galaxy is really a mystery. Half of the core is reddish suggesting strong HII, while the other half is blue suggesting strong star formation. A dark dust band splits the core in two.

But, could this actually be 2 galaxies in the process of merging, ala the Antennae Galaxies? The edge-on perspective makes confirming this difficult. For now, I am assuming that this is a single galaxy with a really strange core.

NGC 6307 is a barred galaxy that is slightly larger than NGC 6306. I like the short arms that are forming at each end of the long bar.

The distance measurements indicate that these two galaxies are about the same distance from us. However, I see no sign of interaction between them.
