NGC 2793

This object is a small ring galaxy located 80 million light years away in the constellation of Lynx at a declination of +34 degrees. This galaxy spans 1 arc-minute in our apparent view, which corresponds to an actual diameter of 30,000 light years.

This galaxy is strange – a bright rectangular offset core, surrounded by a diffuse disk which contains half of a star cluster ring. The galaxy just above and right is PGC 82356. I love the look of the two small galaxies “connected” by a few small orange stars.

Many galaxy rings are believed to be the result of galaxy collisions. Some have speculated that the smaller galaxy in this case may have “punched a hole” in the larger galaxy while passing through it and creating the ring. While this is a very intriguing idea, the reality is that the smaller galaxy is much further away and not interacting with the larger galaxy.

No companion to NGC 2793 has yet to be found, so as of now the source of the ring structure is a mystery.

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.
