NGC 253

This near edge-on grand design spiral galaxy is located only 12 million light years away in the constellation of Sculptor at a declination of -25 degrees. It has a diameter of 95,000 light years and spans almost a half of a degree in our apparent view, about the size of our full moon.

This object is one of the brightest galaxies in the sky. Also known as the Silver Coin, Silver Dollar, and Sculptor Galaxy, astronomers have labeled NGC 253 a starburst galaxy because of the large amount of star formation which is occurring.

From earth's line of sight, the galaxy appears tipped steeply at 80 degrees. It is difficult but not impossible to trace the two spiral arms, which spiral out 360 degrees from a barred core. I find it easier to trace the arms from outside-to-inside for this galaxy.

Many meandering dark dust regions are visible throughout the disk. The large amount of dust in the galaxy disk causes the central region to be more yellow than expected.

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.
