NGC 55 maybe a member of the loosely associated Sculptor galaxy group, a close neighbor of our own “Local Group.” NGC 55 lies only about 6.5M light-years away. It is gravitationally bound to NGC 300, also in my Astrobin collection.

This nearly edge-on view shows dust bands and HII red clouds, and the blue from many young hot stars--NGC 55, apparently, has had a long history of high-rate star production. It is thought to be a barred galaxy, resembling the Large Magellanic Cloud. The distorted shape has be attributed to an abundance of super-novae explosions and extensive strong stellar winds.

Description: Annotated with DSOs from the HyperLeda data base. I used an Excel spreadsheet that I wrote to extract the data from a download and to format it for PixInsight's "AnnotateImage" script.

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.
