NGC 6946 - Fireworks Galaxy

NGC 6946 (Fireworks Galaxy) is a face-on spiral in Cepheus about 25 million light years distant. It is classified as a starburst galaxy. Ten supernovae have been observed in NGC 6946 in the 20th and 21st century - creating the nickname of the Fireworks Galaxy. This supernova rate is about ten times that of the Milky Way even though the Milky Way has twice as many stars as NGC 6946. Some strange objects exist within the galaxy. One such object is a structure called the Hodge Complex (in my image, the blue circular area located above the core - see revision for a closeup). Noted first by Paul Hodge in 1967, it includes a young supergiant cluster. Near the Hodge Complex are areas of strange, crossed dust lanes. The orange star to the lower left of the galaxy is the carbon star MSB 38.

Imaged over several nights: Jun 19-20; Jul 3, 2023.

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.
