PGC 3182 (Gary Imm)

Celestial hemisphere: Northern · Constellation: Cassiopeia (Cas)

PGC 3182

You might think that this Astrobin Debut Object, also known as MCG+12-02-001, is a nebula of some sort. But it is actually a pair of colliding galaxies located 220 million light years away in the constellation of Cassiopeia at a declination of +73 degrees.

Each galaxy spans about 1 arc-minute in our apparent view. This corresponds to a diameter of 60,000 light years.

I have included this object in my GALAXIES - Merger Stage B (Short Bridge) collection. Like many merging pairs, each galaxy has a star stream plume which extends from the core in a direction opposite to the companion galaxy.

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.
