NGC 1421

This object is a nearly edge-on spiral galaxy located 65 million light years away in the constellation of Eridanus at a declination of -14 degrees. This 11.4 magnitude galaxy spans almost 4 arc-minutes in our apparent view, which corresponds to an actual diameter of 72,000 light years.

This was a tough galaxy for capturing detail because of the haze/dust surrounding it. I originally thought that it might be due to poor seeing, but checking the few other images I have found of this object, I think it is just related to this region of the sky.

The core of this galaxy is offset significantly to the right, likely due to the disturbance of a companion object. Likewise, the galaxy arms are not symmetric. The arm on the left side is unusually long and is lit up by an initiation of many bright star clusters and Ha regions. The galaxy seems to have been disturbed by something, but I don't see any obvious candidates nearby. This is some conjecture on a possible companion located in the odd stubby arm at the lower right of the galaxy, but our nearly edge-on perspective makes such a determination difficult.

This is the first image of this object on Astrobin.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
