Vertical Celestial Cascade of Swirling Galactic Arms and Luminous Halo

Full prompt

Vertical deep space telescope observation of a cascading spiral galaxy framed in a 9:16 portrait ratio, tailored as a phone wallpaper with calm upper celestial room. The upper third of the vertical frame remains quiet and uncluttered, filled with deep velvety void and faint cosmological pinprick stars to accommodate interface displays. In the middle and lower quadrants, the iridescent core of the galaxy blazes like a miniature sun in tones of cream, cadmium yellow, and peach, anchoring the downward spiral. Dynamic logarithmic arms sweep downward and across the lower frame, dense with sapphire-blue OB stellar associations, glittering diamond point-stars, glowing magenta emission regions, and dark nebular trenches. The delicate outer halo feathers into the bottom edge with high-contrast depth and pristine astronomical clarity.
