Holmberg 124 is a set of four interacting galaxies that can be found in Ursa Major. Centered in this image is NGC2805. The longest edge-on galaxy is NGC2820 and two smaller nearby galaxies are NGC2814 and IC2458.

NGC2805 is very active with lots of star-forming regions that can be seen particularly throughout the left arm. This activity seems to be recently encouraged by the interactions with the other galaxies in this group.

Faint "whisps" of gases and dust are also visible in the image. This "flux nebula" sits outside of our own Milky Way galaxy but close enough that they are illuminated by the light coming from our galaxy. Sprinkled across this view are also many smaller and more distant galaxy groups.

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.
