NGC 7042 and NGC 7043

This pair of spiral galaxies is located 230 million light years away in the constellation of Pegasus at a declination of +14 degrees. Both galaxy disks are asymmetric and could be close enough to be interacting with each other. We are looking at both of these disks about halfway between edge-on and face-on.

At lower right is NGC 7042, the larger galaxy of the pair at 1.7 arc-minutes wide. This apparent size corresponds to a Milky Way like diameter of 120,000 light years. Its disk structure is bizarrely disturbed – numerous arm fragments, some long and straight, with no strong continuous arms to be seen. Long and straight arm segments are the sign of VV rows, the cause of which are not well understood at this time.

At upper left is NGC 7043, which is just over half of the size of NGC 7042. This galaxy also has an interesting structure. It is a barred ring galaxy but with an discontinuity in the right half of the disk.

At the very bottom right of the frame is a tiny ultra-thin galaxy. If this galaxy is Milky Way size, it is located about 1 billion light years 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.
