NGC 253 - Sculptor Galaxy

NGC 253, with the common name of Sculptor Galaxy, is the brightest member of the Sculptor Group of galaxies.

Visually, NGC 253 is an impressive sight in larger instruments. Its huge envelope is an elongated 25' x 7', and its disk shows complex dust lanes north of the core (lower side of the image).

NGC 253's true size is estimated to be 70,000 light years, comparable to the diameter of the Milky Way. But NGC 253 has a luminosity considerably less than the Milky Way's. The Sculptor Galaxy is a starburst galaxy, which means that it is currently undergoing a period of intense star formation as shown by the red spots illuminated by H alpha at the lower side in the image, which is the side closer to our galaxy.

Version B added H alpha, which better reveals its spiral structure and star forming areas.

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.
