Epic fantasy art of a red supergiant star at the heart of a nebula, swelling with solar flares and looping prominences, its corona a blazing ocean of gold-tinged crimson and incandescent white, dark sunspots swirling on its turbulent surface like ancient eyes, an asteroid belt silhouetted against its burning edge, rays of light piercing through lenticular clouds of superheated gas, a massive rocky planet caught in the star's gravitational embrace, whole scene radiating heat and overwhelming power through scorching orange and deep purple shadows, captured from a vantage point on the edge of a planetary ring, all rendered with the intense, mythical grandeur of a celestial apocalypse.
