NGC253 - The Sculptor Galaxy

NGC253, or the Sculptor Galaxy, is one of the brightest galaxies in our sky. It is an intermediate spiral galaxy in the constellation Sculptor and is roughly 11 million light years away form us.

The Sculptor Galaxy is classified as a starburst galaxy which means there is intense star formation currently occurring within. Several super star clusters (thought to be precursors for globular clusters) are present arranged in an ellipse around the central bulge. Starburst galaxies such as NGC253 that experience strong star formation tend to have material blown out into the galactic halo by stellar superwinds from super massive stars and their eventual supernovas. Curiously, only one supernova has been observed in the Sculptor Galaxy.

While conditions have been slowly improving in Chile, seeing still is not optimal. I tried to overcome this to some extent with brute force on the integration time and careful processing. I am pretty pleased with the result. I hope you like it.

Thanks for stopping by.

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.
