Messier 01 Crab Nebula

A famous and conspicuous supernova remnant who's stellar explosion was recorded by Chinese astronomers in 1054ad. The supernova was powerful enough to have created a neutron star now known as The Crab Pulsar, rotating 30.2 times per second, and emitting x-rays.The supernova was visible in the day for over a month and at night for almost 2 years before fading below naked eye visibility.

The remnant seen here reminds me of a young Cygnus loop (Veil Nebula) another supernova remnant 9000 years old, the similarity in colour and the “string” like structure is apparent although much closer together in the Crab. Estimated to be 6,300 light years away the nebula is 13 x 11 light years across and is expanding at a rate of 1.800 km/sec. The total luminosity in all spectral ranges is over 75,000 suns!!

First discovered by John Bevis in 1731 Charles Messier independently discovered the Crab Nebula in 1758 when he was looking for Haley's comet, after realizing he had mistaken the nebula for the comet he decided to star a catalog of nebula that resembled comets, marking their location in the sky so future comet hunters would not be fooled as he was, the Crab Nebula was his first entry M1.

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.
