NGC 281 A classic Pac-Man

Hi astro-friends,

This is again an image taken back in September 2022, a classic one but always pleasant to look at : NGC 281, aka the Pac-Man Nebula , in the constellation of Cassiopeia, named after the iconic video game from the 80's.

Edward Emerson Barnard discovered the nebula in August 1883, describing it as "a large faint nebula, very diffuse".

According to most recent researches, this bright emission nebula lies about 10’000 l-y away and spans 30 by 30 arcmin in the night sky. There are mostly HII regions ionized by the brightest members of the open cluster, named IC1590, embedded in the center of the nebula and populated by 279 stars. This area is also home of intense star formation in the Bok globules, the dark patches of dense cosmic dust and gas that pop up in front of the nebula.

Clear skies.
Christophe

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.
