Arp 271 Galaxy Duo

Acquisition type: Lucky imaging

Collectively, NGC 5426 is a SAc spiral galaxy and NGC 5427 is a SABc Grand Design intermediate spiral galaxy which is weakly barred, make up Arp 271. The pair are about 130,00 light years across and 130 million light years distant. The kinematics of the pair have been analyzed in detail, showing that the pair are similar masses and relatively weakly interacting, and thus probably unlikely to merge. There is a bridge of material between them that belongs to NGC 5426. It has been proposed that NGC 5427 in moving clockwise (as seen in this image), in the direction of the (trailing) spiral arm rotation, from behind NGC5426 toward the foreground.

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.
