NGC 772

Object #78 in Halton Arp's Atlas of Peculiar Galaxies, also known as NGC 772, is indeed peculiar. One of its many spiral arms is much more developed than the others, due to the tidal forces of its close neighbour galaxy, the elliptical NGC 770.

NGC 772 is an unbarred spiral galaxy about 115 million light-years from us in the constellation Aries. Its diameter is larger than 200000 light-years which is almost twice of the size of the Milky Way. The most prominent feature of the galaxy is the dominant outer spiral arm that is much stronger and more elongated than its other arms. Many HII regions and OB associations can be observed in the stronger arm, though the other smaller and more tightly twisted arms are well formed too, there are not many signs of star formation in them. Several satellite galaxies can be found around NGC 772, one of the closests is NGC 770 a dwarf elliptical galaxy that is thought to be the reason for the asymmetrical appearance of NGC 772.

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.
