Description

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.
More explanations on this event here: https://www.cosmotography.com/images/small_ring_ngc5907.html

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...
