Cet objet est une petite nébuleuse à émission située à 9 000 années-lumière dans la constellation de Céphée. Il est adjacent à la nébuleuse des bulles beaucoup plus célèbre. La plus grande nébuleuse à émission Sh2-159 s'étend légèrement vers le côté gauche de l'image.

La partie la plus intéressante de cette nébuleuse est le petit pilier de nuage (NGC 7538S) qui est vu dans l'étendue la plus éloignée de la nébuleuse vers le bas et vers la droite. Stephen James O'Meara rapporte que des études infrarouges ont révélé qu'il s'agissait d'une très jeune protostar massive. Il est inhabituel en ce qu'il n'a pas encore réchauffé le nuage environnant, de sorte que les scientifiques estiment qu'il pourrait être aussi jeune que 2000 ans.

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.
