galaxy nebula space background purple blue stars
Prompt
Photorealistic deep-space background texture showing a dense star field above glowing interstellar gas clouds, composed with dark near-black cosmos across the top half and soft purple-blue nebula haze drifting through the center. The lower third is filled with layered rust-orange, crimson, and smoky mauve dust, including an abstract vertical dust plume rising from the cloud bank without resembling any known named object. Thousands of tiny white and pale gold stars vary naturally in brightness, with a few crisp starbursts and gentle diffraction spikes. Mood is vast, quiet, and awe-inspiring, with a cool violet, indigo, blue, amber, and copper palette. Simulated long-exposure telescope astrophotography, ultra-sharp stars, fine grain, deep focus, high resolution.
