NGC 7463 Galaxy Trio (Gary Imm)

NGC 7463 Galaxy Trio

This trio of small galaxies are all located about 90 million light years away in the constellation of Pegasus at a declination of +16 degrees. Based on the deformation seen in each of the 3 objects, I believe that these galaxies are interacting.

NGC 7463 is the largest galaxy, but still is only about 50,000 light years in diameter. It has a fascinating barred grand spiral structure, with a yellow core and blue disk. The arms are somewhat distorted, and at each arm end a plume of stars extend into space, further on the right side than on the left.

NGC 7464 is the small 15,000 light year diameter dwarf galaxy just below. It is a mess, likely due to the influence of NGC 7463.

NGC 7465 is the small but bright spiral to the lower left. Faint star streams extend from the galaxy into the lower left region of space. It also looks like it is interacting with NGC 7463.

Two interesting edge-on spirals are seen in the top half of the image, both also disturbed.

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.
