Barred Spirals NGC 4725, & NGC 4747 and NGC 4712 in Coma Berenices

NGC 4725, NGC 4712 and NGC 4747 are located near the north galactic pole in the constellation of Coma Berenices.

NGC 4725 is an intermediate barred spiral galaxy rough 40 million light-years away, and is over 100 thousand light-years across. It has a prominent ring structure, and only has one large arm spiral arm that makes 2-1/2 revolutions around the core.

The smaller galaxy, NGC 4712, is actually physically larger than NGC 4725 in actual size at roughly 150,000 light-years across, but is over 200 million light-years away and hence appears smaller than NGC4725 from our vantage point.

The closest and also smallest of the three in this image is another barred spiral galaxy NGC 4747. It is located at a distance of about 35 million light years from Earth, which, given its apparent dimensions, means that NGC 4747 is about 35,000 light years across.

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.
