Description

This object is a barred spiral galaxy located 70 million light years away in the constellation of Camelopardalis. At a diameter of 80,000 light years, it is not quite as large as our Milky Way. It is fairly small in our sky at an apparent diameter of 6 minutes. This 11th magnitude galaxy is located in the far northern sky at a declination of almost +78 degrees.

I find this galaxy to be fascinating. The detailed, wide, branching brown dust lane is beautiful and stands out against the bright core. Just as interesting are the oddly looping galaxy arms which have been distorted wildly out of plane. Our viewing perspective gives us a perfect angle to see these distorted arms. The arm distortion may be from a close encounter with a smaller galaxy, which could also explain the high rates of star formation that categorize this as a starburst galaxy. I find it odd that this galaxy is not included in the Arp catalog.

One possible encounter candidate is the small bluish spiral galaxy at upper right, NGC 2146a. However, the radial velocities of these two galaxies are so different that a previous interaction between them is unlikely.

I like how the bright foreground Milky Way stars provide a rough arcing path between the two galaxies.
