UGC 8303 (Gary Imm)

UGC 8303

This obscure object is an irregular galaxy located 50 million light years away in the constellation of Canes Venatici. Besides its UGC designation, it is also called Holmberg VIII, one of nine galaxies in the Holmberg catalog detected by Erik Holmberg at the Lund Observatory in Sweden in 1950.

This galaxy is believed to be a satellite of the much larger NGC 5033 galaxy, which is outside of the field of view. I like the odd shape and structure of this galaxy, as well as the contrast of the pinkish star formation areas with the two bright bluish star cluster areas.

In the upper left of the image is galaxy UGC 8314, which is also considered to be a satellite galaxy of NGC 5033. On the right side of the image, looking like a small orange star cluster, is the galaxy group SHK 248. This group has 9 members and is at an average distance of 3 billion light-years.

Looking carefully at the background of the image, you will see many tiny orange-tinted galaxies, some clustered, some not. I have no way of knowing for sure that these are galaxies, but it sure looks like it to me.

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.
