NGC 1954 Galaxy Trio

This object is a rarely imaged triple galaxy system located 140 million light years away in the constellation of Lepus at a declination of -14 degrees. From top to bottom, the 3 galaxies are the red edge-on spiral galaxy IC 2132, the big blue face-on spiral galaxy NGC 1954, and the orange lenticular galaxy NGC 1957. All 3 galaxies are about the same distance away.

My favorite part of this image is the structure of NGC 1954. This galaxy spans 3 arc-minutes in our apparent view, which corresponds to a diameter of 130,000 light years. The galaxy has several interesting concentric oval rings throughout the disk, with the brightest being an outer rim of blue star clusters. I assume that this unique structure was created by the gravitational disturbance with the other galaxies. I like the faint star stream which connects NGC 1954 to the lenticular galaxy below it.

This is the first image of this triple galaxy system on Astrobin.

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.
