Concentric Golden Ratio Cosmic Spiral in Deep Cerulean and Soft Gold

Full prompt

A 3:2 landscape astrophotograph framed for a website hero image, capturing a monumental cosmic vortex structured around an expanding logarithmic spiral. Rather than a tight crop, the majestic core glows serenely toward the left-center, radiating wisps of hydrogen-alpha red and deep cerulean that interlock seamlessly with delicate streams of warm stardust. Micro-filamentary tendrils unwind horizontally across the wide frame, stretching toward the right margin where deep velvet-black space and subtle field stars provide natural breathing room. The illumination stems internally from the calm, concentrated stellar center, revealing soft volumetric gradients and ultra-fine dust textures without violent flares. High-resolution multi-spectral space telescope aesthetics define the composition, highlighting smooth gaseous gradations, layered depth, and controlled celestial luminescence across the expansive horizontal field.
