IC1396 - THE ELEPHANT'S TRUNK NEBULA - LSHO

La nébuleuse de la Trompe d'éléphant est une concentration de gaz interstellaire et de poussière dans une région de gaz ionisé beaucoup plus grande IC 1396, située dans la constellation de Céphée à environ 2 400 années-lumière de la Terre. On pense maintenant que la nébuleuse de la Trompe d'éléphant est un site de formation d'étoiles, contenant plusieurs étoiles très jeunes (moins de 100 000 ans) qui ont été découvertes dans des images infrarouges en 2003. Deux plus vieilles (mais encore jeunes, quelques millions d'années), sont présentes dans une petite cavité circulaire dans la tête du globule. Les vents de ces jeunes étoiles ont peut-être vidé la cavité.L'action combinée de la lumière de l'étoile massive ionisant et comprimant le bord du nuage, et le vent des jeunes étoiles déplaçant le gaz du centre vers l'extérieur, conduisent à une compression très élevée dans la nébuleuse de la Trompe d'éléphant. Cette pression a déclenché la génération actuelle de protoétoiles.(Source Wikipédia)

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.
