NGC 6946, also known as the Fireworks Galaxy, is a spiral galaxy located in the constellation Cepheus. It is notable for its high rate of supernovae discoveries, earning it the nickname "Fireworks Galaxy" due to the frequent appearance of supernovae within its spiral arms. NGC 6946 is approximately 22.5 million light-years away from Earth.The galaxy is characterized by its beautiful spiral structure, with tightly wound arms of gas, dust, and stars extending outward from a bright central bulge. It belongs to the intermediate spiral galaxy classification, displaying features that lie between the barred and unbarred spiral galaxies.NGC 6946 has a relatively high rate of star formation, which contributes to its active nature. It has undergone ten observed supernovae events since 1917, earning it a reputation as a "supernova factory." The presence of these supernovae provides astronomers with valuable opportunities to study the life cycles of massive stars and the dynamics of galactic evolution.

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.
