Detailed view of the Eye of the Cat nebula from Abu Dhabi
The detailed image of the "Eye of Cat" nebula highlights its most prominent and intricate features. It reveals a highly luminous inner structure surrounded by a broad, faint outer halo that indicates successive stages in the end-of-life phase of a star with a mass similar to that of the Sun. The nebula is situated in the Draco constellation, approximately 3,000 light-years from Earth. It reflects the evolution of a red giant star that lost its outer layers and transformed into a white dwarf, with the luminous central region known as the "Eye of Cat" resulting from interactions between stellar winds and the complex gaseous envelope. Studies suggest that the material forming the nebula's outer shell was expelled in earlier phases, prior to the formation of the main nebula, and that the star’s death stages caused gas to disperse over periods estimated at around 1,500 years. This illustrates how planetary nebulae evolve and develop various shapes, possibly influenced by the presence of a companion star affecting the nebula's complex structure.
