galaxy space stars nebula dark
Prompt
Photorealistic deep-space background showing a dense galaxy cluster scattered across a dark cosmic field, with hundreds of tiny star points, softly glowing elliptical galaxies, faint spiral smudges, and delicate blue-white nebula haze drifting through the center. Bright clustered light near the lower-left center fades into inky navy and charcoal space, accented by warm golden galaxy cores and a few crisp diffraction-star highlights. Expansive square composition with no foreground objects, layered depth from pinprick distant lights to larger blurred luminous forms, calm awe-inspiring scientific mood. Color palette of midnight blue, cool silver, misty cyan, and soft amber. Simulated space telescope long exposure, ultra-clean optics, deep focus, high dynamic range without harsh halos.
