Arp 336

This Arp object, also known as NGC 2685, is a Seyfert polar ring galaxy located 40 million light years away in the constellation of Ursa Major at a declination of +59 degrees. It is a magnitude 12.7 galaxy which spans 4 arc-minutes in our apparent view. This corresponds to a diameter of 50,000 light years. It is nicknamed the Helix Galaxy.

A polar ring galaxy is a rare type of galaxy with stars, gas and dust orbiting in rings perpendicular to the primary plane of the galaxy. These perpendicular rings are easy to see in the image. It is believed that polar ring galaxies are the result of a prior galaxy merger.

My favorite parts of this image are the many, distinct, winding parallel dust lanes and the blue star clouds which are developing just to the right of the galaxy core.

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.
