Revision title: Crescent Nebula NGC6888

This emission nebula is most commonly called the Crescent Nebula and it resides in the constellation Cygnus about 5,000 light years away. It’s also sometimes called the Ear nebula or the Euro sign nebula due to its shape. Personally, it reminds me of the Guardians of the Galaxy 2 movie with the big brain floating around in space. It’s a large cosmic bubble about 25 light years across. Its central star is a Wolf-Rayet star, which is a hot, massive star near the end of its life that sheds its outer material and causes a great stellar wind. The structure is thought to be formed by this wind interacting with previously shed material. The blue-green “sack” enshrouding the “brain” is produced by oxygen atoms.

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.
