NGC 6888, nota anche come "Crescent Nebula" è una nebulosa diffusa situata nella Costellazione del Cigno, 2,5 gradi a sud-ovest della stella γ Cygni, dista da noi circa 5000 anni luce. Il nome "Crescent" deriva dalla sua "gobba" che si espande nella direzione di ponente, come il nostro satellite quando è in fase crescente. Questa bolla cosmica, si estende nello spazio per circa 25 anni luce, la stella al suo centro, che probabilmente ha dato vita alla nebulosa è di tipo Wolf-Rayet (stelle massicce con dimensioni di 20 masse solari, che perdono massa molto velocemente producendo violenti venti stellari con velocità di 2000 km/sec.) Questa stella in breve tempo, circa 100.000 anni brucerà tutto il suo combustibile esplodendo alla fine in una maestosa supernova.

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.
