Galaxy NGC3718 (Arp 214) in Ursa Major (2017)

This face on spiral galaxy has a very peculiar morphology and could be the result of a recent merger between two galaxies. The large enveloppe has two diffuse, irregular spiral arms attached. A complex, thin dust lane crosses ESE to WNW in front of the core and appears tidally disturbed. Distance: 47 mly. Diameter: 144000 ly. Angular diameter 10.5'x5.5'

La galaxie NGC3718 dans la grande ourse, image de luminance de 120 mn, C8 avec réducteur (f=1350mm) et ccd CP8-MS. Cette galaxie est distante de 47 millions d'années lumière. La petite galaxie en bas est NGC3729, une spirale barrée distante de 50 millions d'années lumière, vraisemblablement en interaction avec NGC3718. Beaucoup plus lointaines, les petites galaxies en interaction à droite de NGC3718 sont cataloguées sous le nom de UGC6527.

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.
