NGC 4725 est une galaxie spirale barrée intermédiaire avec une structure annulaire proéminente, située dans la constellation nord de Coma Berenices près du pôle nord galactique . Il a été découvert par l’astronome d’origine allemande William Herschel le 6 avril 1785. La galaxie se trouve à une distance d’environ 40 méga-années-lumière de la Voie lactée .NGC 4725 est le membre le plus brillant du Coma I Group du Coma-Sculptor Cloud, bien qu’il soit relativement isolé des autres membres de ce groupe. Cette galaxie est fortement perturbée et interagit avec la galaxie spirale voisine NGC 4747, avec ses bras spiraux montrant des signes de déformation. La paire a une séparation angulaire de 24′ , ce qui correspond à une séparation linéaire projetée de 370 kly . Un panache de marée s’étend de NGC 4747 vers NGC 4725.

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.
