NGC 5907 also nicknamed the "Splinter Galaxy" is a spiral galaxy seen from the edge and located in the constellation of the Dragon at about 30 million light years from the Milky Way.

This galaxy has a huge but very faint trail of stars surrounding it. It is certainly the remains of a collision or an old merger of NGC 5907 with a dwarf galaxy.

NGC 5905 and NGC 5908 (on the right) are much further away, about 150 million light-years...

-------------------

NGC 5907 aussi surnommée la "galaxie de la Lame de couteau" est une galaxie spirale vue par la tranche et située dans la constellation du Dragon à environ 30 millions d'années-lumière de la Voie lactée.

Cette galaxie présente une immense mais très faiblement lumineuse trainée d'étoiles qui l'entoure. Il s'agit certainement des restes d'une collision ou d'une fusion ancienne de NGC 5907 avec une galaxie naine.

NGC 5905 et NGC 5908 (à droite) sont quant à elles bien plus éloignées, à environ 150 millions d'années-lumière...

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.
