Silver Coin Galaxy in Sculptor

The Sculptor Galaxy is a little over 11 million light years from us and is located at the center of the Sculptor Group, one of the nearest groups of galaxies to the Milky Way. It is the brightest galaxy in the group and one of the intrinsically brightest nearby galaxies.

The Sculptor Galaxy is an example of a starburst galaxy, that is, one which is undergoing a period of intense star formation. This has created several super star clusters on NGC 253's centre, one with a mass of 1.5 x 10^6 solar masses, and absolute magnitude of at least -15, and two others with 5 x 10^4 solar masses and absolute magnitudes around -11. Star formation is also high in the northeast of NGC 253's disk, where a number of red supergiant stars can be found. In its halo there are young stars as well as some amounts of neutral hydrogen. This, along with other peculiarities found in NGC 253, suggest that a gas-rich dwarf galaxy collided with it 200 million years ago, disturbing its disk and starting the present starburst.

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.
