sh2-136 (Nébuleuse du Fantôme - Ghost Nebula)

La nébuleuse fantôme Sh2-136 (également connue sous le nom de vdB 141) est une nébuleuse par réflexion située à environ 1 470 années-lumière dans la constellation de Céphée. La poussière et le gaz de la nébuleuse forment des figures étranges qui ressemblent à des fantômes représentés dans la culture populaire.
La nébuleuse fantôme s'étend sur plus de 2 années-lumière et est éclairée par plusieurs étoiles proches. Elle représente un globule de Bok, c’est-à-dire un nuage de matière froide et dense avec des nœuds plus denses qui peuvent s'effondrer et former de nouvelles étoiles. Les globules de Bok produisent généralement des systèmes stellaires binaires et multiples.
Cette nébuleuse est cataloguée sous le nom de Bok globule CB230 et contient une étoile en formation. La présence de l’étoile est indiquée par des jets de matière qui sont sculptés par le vent, les rayons ultraviolets et le disque de matière tourbillonnant autour de la jeune étoile.

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.
