Hickson 86 (Gary Imm)

Celestial hemisphere: Southern · Constellation: Sagittarius (Sgr)

Hickson 86

This Astrobin Debut Object is a small galaxy group located 280 million light years away in the constellation of Sagittarius at a declination of -31 degrees. All 4 of these galaxies are classified as elliptical or lenticular galaxies. The largest galaxy, Hickson 86A, spans 1 arc-minutes in our apparent view, which corresponds to a diameter of 80,000 light years.

Although these galaxies are close enough together to be considered a group, the data shows that they are still millions of light years apart. None of them appear to be disturbed. The galaxy in the upper right corner should also be included in this group, since it is about the same distance 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.
