Fishhook Galaxy (Gary Imm)

Celestial hemisphere: Northern · Constellation: Cancer (Cnc)

Fishhook Galaxy

This Astrobin Debut Object is a tiny, unusually distorted starburst galaxy located 650 million light years away in the constellation of Cancer at a declination of +28 degrees. It spans 30 arc-seconds in our apparent view. This corresponds to a Milky Way size diameter of 120,000 light years. The bottom tip of the galaxy is obstructed slightly by a foreground Milky Way star.

Its formal names are AGC 181313 and SDSS J082355.03+280630.5. It looks more like a saxophone than a fishhook to me.

So many mysteries abound in the universe. The galaxy structure here is one of them. I don’t understand how it formed. It looks a bit like a pair of galaxies merging, with long tails, but those tails contain far more dust than would be expected if that were the case.

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.
