Due to the fact that all kinds of remakes and remasters are currently in vogue, I decided to make a third attempt at the highly beloved and photogenic NGC6888 - the Crescent Nebula , although I personally see it more as a brain or a jellyfish floating in a hydrogen ocean 😉. This cosmic bubble located in the constellation of Cygnus has a diameter of approximately 25 light-years and is the result of the outer layers being expelled by the very hot and massive Wolf-Rayet star WR136, which evolved from a red dwarf. This process led to the shedding of the outer shell through a strong stellar wind at a rate equivalent to the mass of the Sun every 10,000 years. Thus, the stellar wind collided with the surrounding gas left over from the previous phase, compressing it into a series of complex shells and further ionizing them through the ultraviolet flux of the central star. The nebula itself belongs to the category of emission nebulae. Its color is attributed to hydrogen and oxygen atoms. Oxygen atoms are the source of the bluish-green hue surrounding the hydrogen (red) folds and filaments.

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.
