M1 The Crab nebula

Messier 1, the Crab Nebula, was created in 1054 by a supernova explosion. Word is that the resulting conflagration was visible during the daytime for three weeks, and at night for nearly 2 years. The date is remarkable too, July 4th, that would have been some fireworks show!

This Crab is about 7000 light years away. Aside from the usual hydrogen in red, and oxygen in green, the Crab also emits synchrotron radiation, which is producing by fast moving and thus high-energy electrons that are forced into curved lines in a strong magnetic field. This results in the visible in a continuum of blue emission.

This image was taken over a horrible winter, with hazy skies and poor seeing, so I was pleased to get anything at all decent out of this image (on the plus side, I have had plenty of time to optimize the image processing). Got to look on the Brightside (or is it Darkside?).

Clear skies.

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.
