NGC 2685 is a very unusual galaxy in the constellation Ursa Major.
It is a rare polar ring galaxy - meaning it has a ring of gas, stars and dust orbiting in a plane almost perpendicular to the normal flat plane of NGC 2685. Physically it contains two separate velocity systems whose axes are perpendicular. The most popular view says that such galaxies are the result of an interaction, up to and including a complete merger, with another galaxy.
This feature can be seen in the image as helical filaments around the central part of the galaxy.
NGC 2685 is about 50,000 light years across, and about 42 million light years from Earth.

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.
