The Silver Dollar Galaxy, NGC 253 (The Sculptor Galaxy, Caldwell 65, PGC 2789)

The Silver Dollar, or Sculptor Galaxy is one of the brightest galaxies in the sky, and thus has been known
for quite a long time. It was recorded first by Caroline Herschel in 1783 and is known as a “starburst”
galaxy, meaning that it is undergoing intense star formation.

NGC 253 is the prototype of a special group of spiral galaxies in which the sprial arms are often defined
by “dust lanes” and areas of great complexity, rather than the usual luminous gas and nebulae in typical
spiral galaxies. It, along with five other galaxies which includes the Needle’s Eye Galaxy (NGC 247), form
the gravitational centre of the Sculptor Galaxy Group, our nearest galaxy grouping. It lies some 11.4
Mly away. The sturbust activity is located in a large number of places in the galaxy’s halo. It is believed
that this could have been triggered by the collision with a dwarf galaxy some 200 My ago.

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.
