SN2023ixf - Supernova in M101 - The Pinwheel Galaxy

Back during the time when dinosaurs roamed the earth a single aging supergiant star in a galaxy of a trillion stars ran out of fuel and exploded in a Type II core collapse Supernova.

I had not planned to capture this image but M101 is still favourably positioned in the night sky, a real-time supernova is a fairly unique astrophotography event for a simple backyard astrophotographer, and we were lucky enough to have a few clear, but somewhat moonlit, nights. Given the less than ideal data due to the bright moon and the longterm weather forecast I combined the data from two scopes - first time. Processing showed an obvious gradient due to the moonlight and the outer blue arms of the galaxy are somewhat attenuated.

M101 - the Pinwheel Galaxy - is a large, very photogenic, spiral galaxy 21 MY lightyears distant in the constellation Ursa Major - the Big Bear. But the 'star?' of the show is SN2023ixf.

So an event that happened literally millions of years ago and trillions of kilometers away is affecting the time and energy of my insignificant earthling human life - and now yours too - because you are reading this.

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.
