NGC 6946, also known as the Fireworks Galaxy, is a celestial marvel located approximately 22.5 million light-years away from Earth in the direction of the Cepheus constellation. This stunning spiral galaxy has earned its nickname due to its remarkable history of frequent supernova explosions, making it a celestial fireworks display like no other.One of the most remarkable features of NGC 6946 is its impressive spiral structure, characterized by its swirling arms of stars, dust, and gas. Its face-on orientation towards Earth provides astronomers with a unique perspective to study its structure and star formation processes.What sets NGC 6946 apart from many other galaxies is its propensity for supernovae, the dramatic explosions of massive stars. Over the past century, astronomers have observed ten supernovae within NGC 6946, earning it the title of the "Fireworks Galaxy." This high frequency of supernovae within a single galaxy is a rare phenomenon, making NGC 6946 a hotbed for studying the life cycles of massive stars.

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.
