NGC 810

This object is an unusual elliptical (E2) galaxy located 360 million light years away in the constellation of Aries at a declination of +13 degrees. It is a magnitude 14 galaxy which spans 1.1 arc-minutes in our apparent view. This corresponds to a Milky Way sized diameter of 120,000 light years.

It appears that this is a recent/ongoing merger object, for 2 reasons. First, a second small bright core is seen just to the left of the NGC 810 core. Second, this galaxy is one of the few which shows prolate rotation – it is rotating around its long axis. This is seen in the data but more obviously in the striking dust lane, which is the only one I have seen running perpendicular to its long axis. With time, scientists believe that the prolate rotation will dissipate.

Surprisingly, 3 other galaxies in this image also appear disturbed – UGC 1593 to the left, UGC 1584 at top, and PCG 212910 to the right.

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.
