Hickson 82

This Astrobin Debut Object is a galaxy quartet located 0.5 billion light years away in the constellation of Hercules at a declination of +33 degrees.

The bright large elliptical galaxy near the center of the image is NGC 6162 / Hickson 82a. This galaxy spans 1.2 arc-minutes in our apparent view, which corresponds to a huge diameter of 200,000 light years.

The other 3 galaxies here are all smaller but more interesting in structure. The barred spiral ring galaxy to the left is NGC 6163 / Hickson 82b. It is slightly smaller than NGC 6162. The odd looking galaxy below is NGC 6163 / Hickson 82. This is a fascinating one with a large dust lane – it looks like a late stage galaxy merger to me. Finally, the edge-on barred spiral at lower right is LEDA 58231. It has a large bulge.

Except for the merged galaxy, none of these galaxies show much in the way of disturbance despite being members of the same cluster.

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.
