NGC 7635, également connue sous le nom de nébuleuse de la Bulle, est une nébuleuse d'environ 10 années-lumière de diamètre située dans la constellation de Cassiopée.
Elle est composée d'hydrogène ionisé, c'est une région HII.
Elle a été découverte en 1787 par William Herschel.
Située près de l'amas ouvert Messier 52, cette nébuleuse ressemble à une bulle.
Elle est formée par le vent stellaire créé par l'étoile SAO 20575 (BD+60 2522) à une vitesse de plus de 1 700 km/s.
Cette étoile, excentrée par rapport au nuage, est la plus brillante.
Elle est très jeune (moins de 4 millions d'années), très chaude (environ 35 000 degrés) et massive (de 20 à 40 fois la masse solaire).
L'étoile n'est pas au centre car le nuage en expansion rencontre une région plus dense et plus froide sur un côté.
Elle devrait exploser en supernova dans 10 à 20 millions.

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.
