NGC 281 Pacman Nebula

Beschreibung:

NGC 281 ist ein Emissionsnebel im Sternbild Kassiopeia, welcher 9500 Lichtjahre von der Erde entfernt ist. Der Nebel ist im Index-Katalog als IC 11 und erfasst wird umgangssprachlich wegen seiner Ähnlichkeit mit der gleichnamigen Videospiel-Hauptfigur vor allem im englischen Sprachraum auch als Pac-Man-Nebel bezeichnet. In NGC 281 ist der offene Sternhaufen IC 1590 eingebettet, dessen Sterne um das Zentrum des Nebels verstreut sind. Das hellste Mitglied von IC 1590, das Mehrfachsternsystem BD +55° 191 (HD 5005), ist die ionisierende Quelle des Nebels. Der Nebel enthält auch mehrere Bok-Globulen, in denen durch Infrarotaufnahmen Anzeichen für Sternentstehung festgestellt werden konnten.

NGC 281 wurde am 16. November 1881 vom amerikanischen Astronomen Edward Emerson Barnard entdeckt.

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.
