IC-63 "The Ghost of Cassiopeia"

Powerful gushers of energy from seething stars can sculpt eerie-looking figures with long flowing veils of gas and dust. One striking example is
"The Ghost of Cassiopeia," officially known as IC 63, located 550 light-years away in the constellation Cassiopeia the Queen.

The nebula’s ethereal glow might remind people of apparitions such as those reported by paranormal investigators. In reality, it's simply
hydrogen that is being bombarded with ultraviolet radiation from the nearby, blue-giant star Gamma Cassiopeiae (Navi), causing it to glow in red light.
The blue color is from light reflected off of the nebula’s dust.

The IC 63 nebula is not the only object under the influence of the blinding star, which unleashes as much energy as 34,000 suns. The Ghost Nebula
is part of a much larger nebulous region surrounding Gamma Cassiopeiae that measures approximately two degrees on the sky — roughly four times
as wide as the full Moon

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.
