M1 - The Crab Nebula

M1, the Crab Nebula, is the result of a star that exploded in 1054 AD. It was recorded by astronomers in China as a “guest star” in the constellation Taurus. The supernova explosion was visible during the day for three weeks and was visible to the naked eye at night for two years before fading from view. A pulsar rotating 30 times per second was formed as a result of the supernova. The remnant nebula is about 10 light years across and still expanding, with changes to its structure visible over the course of days. It lies about 6,500 light years from Earth. In 1928, Edwin Hubble proposed that the nebula was associated with the “guest star” from 1054 AD. This was later proved by Nicholas Mayall.

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.
