Der Irisnebel (NGC 7023) und der Geisternebel (VDB 141) im Sternbild Kepheus bieten beeindruckende Anblicke. Der Irisnebel zeigt eine Mischung aus blauen Reflexionen und zartem Magenta, verursacht durch Staubkörner, die Licht reflektieren und Ultraviolettstrahlung absorbieren. Infrarotbeobachtungen deuten auf komplexe Kohlenstoffmoleküle hin. Der Geisternebel, beleuchtet von zahlreichen Sternen, enthält Gebiete, in denen Staub und Gas neue Sterne bilden. Beide Nebel liegen etwa 1.200 bis 1.300 Lichtjahre von der Erde entfernt und bieten Einblicke in die Entstehung und Entwicklung von Sternen.

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.
