NGC6888 aka The Crescent Nebula aka Caldwell 27 aka Sharpless 105

The Crescent Nebula is an emission nebula in the constellation Cygnus, about 4700 light-years away from Earth. It is formed by the fast stellar wind from the Wolf-Rayet star WR 136 (HD 192163) colliding with and energizing the slower moving wind ejected by the star when it became a red giant around 400,000 years ago.

Pusmėnesio ūkas - tai emisinis ūkas Gulbės žvaigždyne. Jis nutolęs nuo Žemės apie 4700 šviesmecių. Ūkas susiformavo aplink Wolf-Rayet tipo žvaigždės WR 136 (HD 192163) dėl lėčiau judancių dujų, numestu siuo raudonu gigantu pries apytiksliai 400 tukstančiu metu, ionizacijos, sukeltos susidurimu su greitai judanciu zvagzdės veju.

Туманность Полумесяц - это эмиссионная туманность в созвездии Лебедь. Она располагается на расстоянии примерно 4700 световых лет от Земли. Туманность образовалась вокруг звезды WR 136 (HD 192163) типа Вольфа-Райе в результате ионизации быстрым звёздным ветром медленнее движущегося газа, сброшенного этим красным гигантом около 400 тысяч лет назад.

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.
