The nebula called "Cassiopeia's Ghost" was photographed from the Abu Dhabi desert, by Al Khatam Astronomical Observatory.

The nebula consists mostly of ionised hydrogen. It appears red due to ultraviolet rays coming from a giant blue star near it that does not appear in the image (Gamma Cassiopeia), and the light blue colour is due to the reflection of rays from the dust in the nebula, the Abu Dhabi-based International Astronomical Centre said on X.

The image was taken using the main observatory telescope with a diameter of 36 cm.
