M16 Adlernebel (Sternwarte Deidesheim)

M16 Adlernebel

Der Adlernebel oder IC 4703 ist ein Nebel in Verbindung mit einem offenen Sternhaufen. Der offene Sternhaufen trägt im Messier-Katalog die Bezeichnung M16 bzw. im NGC die Nummer NGC 6611. In vielen Katalogen werden Nebel und Sternhaufen gleichbedeutend aufgeführt, so dass die Messier-Katalog-Bezeichnung meist auch für den Nebel verwendet wird. Er befindet sich im Sternbild Schlange.=x11i5rnm xat24cr x1mh8g0r x1vvkbs xtlvy1s x126k92a=x193iq5w xeuugli x13faqbe x1vvkbs x1xmvt09 x1lliihq x1s928wv xhkezso x1gmr53x x1cpjm7i x1fgarty x1943h6x xudqn12 x3x7a5m x6prxxf xvq8zen xo1l8bm xzsf02u x1yc453hDer Adlernebel ist von der Sonne etwa 7000 Lichtjahre entfernt.

Er besteht hauptsächlich aus Wasserstoff, der sich auf Grund der geringen Temperatur zu Wasserstoffmolekülen zusammenschließen konnte. Der ca. 20 Lichtjahre große Nebel enthält Staubsäulen, die bis zu 9,5 Lichtjahre lang sind und an deren Spitze sich neue Sterne befinden, weshalb sie auch Säulen der Schöpfung getauft wurden. Die Undurchsichtigkeit des Nebels kommt durch Silikat und Kohlenstoffpartikel zustande. Das mittlere Alter der Sterne liegt bei etwa 800.000 Jahren. Einige Sterne sind sehr jung, das Alter der jüngsten Sterne wird auf 50.000 Jahre geschätzt. (Wiki)

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.
