This nebula, located in the constellation Cassiopeia, arises from the interaction between the stellar wind of a young massive O-type star and the surrounding gas which is repelled, creating its characteristic bubble shape.
 
The stellar wind is extremely massive and compresses the gas of the nebula surrounding it while the very energetic radiation strongly ionizes the latter. The bubble therefore materializes the place where this phenomenon occurs. 
 
The star at the origin of this celestial object is of a particular type since we speak of a "Wolf-Rayet" star. It has the particularity of being very hot and of having entered the end of life phase after its main sequence. At this point in its life, it has finished consuming its basic fuel which is hydrogen. If it is sufficiently massive, it will then begin to trigger helium fusion reactions which, once exhausted, will cause a contraction of the core and an increase in temperature, thus transforming it into a white dwarf.
 
The image was produced in Hubble palette, that is to say in sho, in order to better bring out the different layers and the structure of the image. Its relatively small size makes it a complicated object to photograph. The guidance needs to be excellent in order to capture as much detail as possible.
