Arp 277 (Gary Imm)

Celestial hemisphere: Northern · Constellation: Virgo (Vir) · Contains: NGC 4809 · NGC 4810

Arp 277

This Astrobin Debut Object is a pair of interacting irregular galaxies located 45 million light years away in the constellation of Virgo at a declination of +3 degrees. In his Arp catalog, Dr. Arp classified this object into the category of Interacting Double Galaxies.

The top galaxy is NGC 4809. This magnitude 14 galaxy spans 2 arc-minutes in our apparent view, which corresponds to a diameter of 25,000 light years. The bottom galaxy is NGC 4810. This magnitude 15 galaxy has a diameter of 15,000 light years.

A surprising amount of structure is visible in both of these galaxies. Numerous blue star clusters are seen, likely initiated from the interaction of these 2 objects. The galaxies look to be connected by a star stream bridge, although our single view persepctive doesn’t allow us to confirm this.

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.
