NGC 281 is an emission nebula located in the constellation Cassiopeia, informally known as the Pacman Nebula due to its striking resemblance to a popular video game protagonist. It spans 48 lightyears across and contains several Bok globules as well as a small, open star cluster (IC 1590). Dark lanes of dust cutting into bright clouds of gas create the trademark “mouth” shape that gives the nebula its nickname.

NGC 281 was first identified in 1883 by American astronomer and astrophotographer E.E. Barnard. Barnard, best known for his discovery of Barnard’s Star3 in 1916, noted NGC 281 as, “a large faint nebula, very diffuse,” upon discovering it.

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.
