Arp 99 - Hickson 93

This object is a galaxy group of three primary members located 230 million light years away in the constellation of Pegasus at a declination of +19 degrees. The cluster is dominated by the influence of the huge elliptical on the left side (NGC 7550). The elliptical width in our apparent view is 3 arc-minutes which corresponds to a true width of 200,000 light years. Its gravitational impact on the 2 spiral galaxies to the right (NGC 7549) and below it (NGC 7547) are seen in the faint star streams which extend from each of these galaxies towards the elliptical, along with some deformation of the spiral arms of both galaxies.

The three small galaxies across the top of the image are not related to this group.

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.
