Voici la nébuleuse WR 134, dans la constellation du Cygne.

Il s'agit d'une étoile variable en fin de vie, environ 400 000 fois plus lumineuse que le Soleil et qui éjecte périodiquement de grandes quantités de matière sous forme de vent stellaire à haute vélocité.

A ce stade, le vent stellaire et le rayonnement génèrent et illuminent des structures dans l'environnement proche de l'étoile, matérialisées ici par la "boucle" bleue, qui n'est en réalité que la partie la plus visible d'une sorte de "bulle" plus ténue et difficile à mettre en évidence. Cette activité dure environ 1 million d'années avant que l'étoile n'explose en supernova.

Photo réalisée au cours de l'été dernier, en HOO + RGB pour les étoiles, Environ 17h de pose en Ha 3,5nm et 15h en OIII (4,5nm). 35h de pose au total.

Cette image a été primée AAPOD2 (27 oct. 2020).

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.
Dismissals 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.
