M1 Crab Nebula #6 (Bicolor)

M1, the Crab Nebula!

This unique and intricate nebula is actually the remnant of a supernova that was observed here on Earth in the year 1054 by Chinese astronomers, as well as possibly Japanese and Middle Eastern astronomers. Its unusual brightness this long beyond the supernova is explained by the pulsar that the exploding star became, a rapidly-spinning neutron star whose relativistic stellar wind energizes the nebula. As a result, the Crab Nebula glows brightly all across the spectrum, from radio waves through high-energy gamma rays.

Number 1 on Messier's list of objects that aren't comets, the Crab Nebula is located in Taurus, and can be seen with any size of telescope under moderately dark skies. It lies about 6,500 lightyears away, and is about 11 lightyears across.

This image is a composite of hydrogen-alpha (Ha), oxygen-III (OIII), and RGB color stars. The Ha data were assigned to the red channel, and OIII to green and blue. This color combination gives the nebula a natural look, since visible hydrogen glows a deep red, and oxygen glows a blue-green. These narrowband channels pierce through the light pollution of the Bay Area much more effectively than my wideband color filters, giving me a lot more detail!

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.
