IC1396 Elephant Trunk Nebula

Der Elefantenrüsselnebel, auch bekannt unter der Katalogbezeichnung IC 1396A, ist eine hell berandete Globule, also eine Ansammlung von interstellarem Gas und Staub, im Sternbild Kepheus. Die Globule gehört zu IC 1396, einem H-II-Gebiet mit eingebettetem Sternhaufen, und ist etwa 2400 Lichtjahre von der Erde entfernt.Der Nebel ist ein aktives Sternentstehungsgebiet und enthält eine Reihe junger Sterne und Protosterne, die erst zwischen 100.000 und einer Million Jahre alt sind. [2]Vor der Globule befindet sich der Reflexionsnebel van den Bergh 142 (vdB 142), der sehr wahrscheinlich in physikalischem Bezug steht. Dieser Reflexionsnebel wird vom B3-Stern HD 239710 (BD +56° 2604) angestrahlt. Die Bezeichnung vdB 142 wird oft für den Elefantenrüsselnebel angegeben, was jedoch falsch ist.

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.
