"name": "This image presents a stunning deep space view centered on the Cat’s Eye Nebula, with intricate structures and vibrant colors. The nebula itself glows in an ethereal blue and violet hue, surrounded by delicate, symmetrical, and concentric gaseous layers that form its iconic shape. The surrounding space is filled with an intricate web of faint reddish and brownish wisps on the outer region surrounding the nebula. Bright stars with distinct diffraction spikes punctuate the scene, adding depth and contrast to the dark, star speckled background. Numerous galaxies are also visible in the background. The image showcases a great balance between sharp details in the nebula's core and the softer, ghostly tendrils of interstellar gas beyond.",
