Bubble-Nebel NGC 7635

Siehe Wikipedia
NGC 7635, auch Blasennebel (engl. Bubble Nebula) genannt, ist ein Emissionsnebel und eine HII-Region im Sternbild Kassiopeia am Nordsternhimmel, welcher etwa 7100 Lichtjahre von der Erde entfernt ist. Er befindet sich in der Nähe des offenen Sternhaufens Messier 52. Die Bezeichnung stammt von einer Sternwind-Blase, die durch den Sternwind eines O-Sterns mit der Bezeichnung BD +60 2522 (SAO 20575) entstanden ist. Der Stern stößt große Mengen an Gas aus, die sich mit rund 28 Kilometer pro Sekunde in die Umgebung ausbreiten. Dabei stoßen die expandierenden Gase auf die riesige umgebende Molekülwolke in dieser Region, die der Ausdehnung Widerstand entgegenbringt. Dadurch bildet sich eine Stoßwelle aus, welche die äußere Hülle der Gasblase bildet.

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.
