Hickson 90 Galaxy Group

This object is located 100 million light-years away in the southern constellation of the Piscis Austrinus (the Southern Fish) at a declination of -32 degrees. The galaxy group consists of the three small NGC galaxies below the center of the image - a distorted dusty spiral galaxy (NGC 7174) caught between two large elliptical galaxies (NGC 7173 above, and NGC 7176 adjacent). This gravitational battle will eventually likely result in the merger of the trio into a large single galaxy.

This small grouping is best left to the Hubble to image, but I couldn't resist trying to capture it anyway. My favorite part of the image is the dust band of NGC 7174.

Other galaxies are also visible in this image, including the interesting spiral NGC 7172 above. This galaxy has a thick, gracefully curving dust band and a bright active core.

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.
