Sh2-171

Cet objet est une grande nébuleuse à émission située à 3000 années-lumière dans la constellation de Céphée à une déclinaison de +67 degrés. La nébuleuse s'étend sur 75 minutes d'arc dans notre vue apparente, ce qui correspond à une véritable étendue de 65 années-lumière. Le complexe est parfois appelé Sh2-171 et Cederblad 214, bien que les véritables limites de ces objets soient légèrement différentes.

De nombreux "troncs d'éléphants" - piliers cosmiques de gaz froid et de poussière noire - se trouvent dans cette nébuleuse. Tous ces troncs pointent vers l'amas d'étoiles Berkeley 59 vers le haut de l'image. Les vents puissants et le rayonnement de cet amas d'étoiles sculptent et érodent les formes denses des piliers.

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.
