Hickson 88

This object is a rarely imaged galaxy group located 300 million light years away in the constellation of Aquarius at a declination of -6 degrees. The group consists of four spiral galaxies. From top left to lower right, the galaxies are NGC 6978, NGC 6977, NGC 6976 and PGC 65612. Each galaxy is about 1 arc-minute in size, which corresponds to a true diameter of 90,000 light years.

Looking closely, all 4 of these galaxies are not quite symmetric. They may have been slightly disturbed through interaction, perhaps with each other. Several other faint galaxies, seen as smudges, are also visible and are believed to be part of this group as well.

I like the tiny, much more distant orange galaxies which are visible in the background, especially near the center of the image. These galaxies are over 2 billion light years away.

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.
