La nébuleuse du Croissant ou NGC 6888 est une nébuleuse en émission située dans la constellation du Cygne, à environ 5 000 années-lumière2. Elle est issue des rapides vents stellaires créés par l'étoile Wolf-Rayet WR 136 , qui poussent la matière issue de vents plus lents éjectés par cette même étoile lorsqu'elle était plus jeune et plus petite (de type géante rouge) il y a 400 000 ans. Le front de choc engendre ce que l'on nomme une bulle de Wolf-Rayet. La nébuleuse est principalement ionisée par l'étoile centrale qui a une température de surface de 70 000K.
On trouve également La nébuleuse de la Bulle de savon, ou PN G75.5+1.7, est une nébuleuse planétaire.

----------------------------------------------------

The Crescent Nebula or NGC 6888 is an emission nebula located in the constellation Cygnus, about 5,000 light-years away. It is from the fast stellar winds created by the star Wolf-Rayet WR 136, which pushes the material from slower winds ejected by this same star when it was younger and smaller (red giant type) ago 400,000 years old. The shock front generates what is called a Wolf-Rayet bubble. The nebula is mainly ionized by the central star which has a surface temperature of 70,000K. Also found is The Soap Bubble Nebula, or PN G75.5+1.7, is a planetary nebula.

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.
