The NGC 281 nebula ("Pacman Nebula") is a star formation site in the direction of the Cassiopeia constellation. It is possible to see in the image the IC 1590 open cluster (in the center), which formed only a few million years ago. The brightest star in this cluster is a binary system, whose energy ionizes the gas that makes up the nebula. The blue color corresponds to the emission of double-ionized oxygen and the color "orange" to the ionized sulfur. The dust zone to the right of the center probably hides stars in the process of forming. Bok globules against the brightest background of the nebula are also perfectly visible. The distance to NGC 281 is about 10,000 light years.

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.
