Gamma Cassiopeiae Nebula in HaRGB

Gamma Cassiopeiae Nebula (IC 63 and IC 59)

This nebula complex surrounding the star 'γ-Cassiopeiae' or 'Navi' (the brightest star in the image) consists of an emission nebula (IC 63) and a reflection nebula (IC 59).

IC 63 is the red 'ghostly apparition' in the center of the image and IC 59 is the blue nebula on the left.

The star γ-Cassiopeiae is a variable sub-giant star, at a distance of ~550 light-years, which is rapidly spinning with a rotational velocity of ~500 km/s (1000 times faster than Earth's rotation).

The radiation from the star ionizes the surrounding gas, creating this 'ghostly' nebula complex.

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.
