NGC 4411 & UGC 7546

This object is a pair of small face-on spiral galaxies located 50 million light years away in the constellation of Virgo at a declination of +9 degrees. Each galaxy spans about 2 arc-minutes in our apparent view.

NGC 4411 is the slightly smaller galaxy on the right. Strange that the smaller object was the only one given an NGC number, although it is a prettier barred grand spiral galaxy. Also strange is that, based on the established distance for these galaxies, the diameter of this galaxy is only 40,000 light years. Galaxies that small usually don’t show this much structure. I think that these galaxies may be further away than 50 million light years.

I love the structure of NGC 4411 – each arm of the 2 arms is distinct and symmetric, extending more than 360 degrees around the core. The structure of UGC 7546 is a bit more disturbed, yet neither galaxy is as disturbed as they should be if they are at the same distance. This is another reason why I think the distance estimates here are suspect.

Many other galaxies are seen in the background, some of which are identified in the Astrobin mouseover. One of my favorites is the distant galaxy cluster in the upper left corner.

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.
