NGC 253 is another "star-burst" galaxy that exhibits extensive star-formation activity. As with many (most?) star-burst galaxies, the disruption of their organized spiral structures in NGC 253 has made identifying spiral arms very difficult. Instead, the galactic disk appears tumultuous and rugged. The galaxy's circumference hosts numerous blue areas. Probably these blue areas are clouds acting as reflection nebula for young, bright stars. Interspersed with the blue nebulae lie abundant red emission nebulae. This geometry suggests massive star formation at the galaxy's rim and may explain the misty halo of dust, gas, and stars that envelop the galaxy. Most probably, the high winds accompanying the star formation have ejected this cloud from the galaxy.

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.
