Design a terrifying yet mesmerizing cosmic nightmare, where alien life, stars, and planets exist in a dark, hostile universe. The sky above should be a chaotic swirl of deep, unsettling colors—blood-red nebulae and pitch-black voids, broken only by clusters of dying stars that flicker weakly. Massive, broken planets hang ominously in the distance, their surfaces cracked and crumbling, leaking streams of toxic, glowing gases in sickly shades of green and violet, casting a ghostly light over the entire scene. The landscape below is a barren, alien wasteland of jagged, obsidian cliffs and gaping chasms, with rivers of molten lava running through the cracks, glowing a sinister, fiery red. Sharp, twisted formations of rock rise from the ground like claws reaching for the sky. The ground itself seems alive, with patches of dark, writhing alien vegetation—spindly, thorny vines that curl and twitch, as if searching for prey. Lurking among the twisted terrain are grotesque alien creatures, barely visible in the shadows—tall, skeletal figures with elongated, insect-like limbs, their skin shimmering with oily black and dark purple hues. Their glowing, hollow eyes pierce through the darkness, following the viewer's gaze, giving the sense that they are being watched, stalked by something otherworldly and malevolent. Their movements are slow and deliberate, accompanied by eerie, whisper-like sounds that echo through the vast, empty landscape. At the center of this horrifying scene, a colossal alien structure rises from the ground—an ancient, decaying temple-like spire, its surface etched with disturbing, pulsating symbols that glow in sickly greens and blues, casting an eerie, unnatural light. The structure seems to hum with a dark energy, radiating a sense of doom, as if it holds some forbidden, cosmic secret. Shadows seem to slither and move around it, hinting at something monstrous hidden within. Above, the sky is filled with swirling asteroid fields and chaotic cosmic storms. Massive comets streak past, leaving trails of burning red and blue, while dark cosmic clouds pulse with lightning in unnatural colors—deep violet and electric blue. In the distance, a massive black hole consumes a nearby star, pulling everything around it into its gaping maw, distorting the light and space in a slow, terrifying spiral. The entire scene should evoke sheer dread—a dark, alien world where every element feels hostile and alive, with vivid, dark colors adding to the sense of fear. The universe itself feels like a predator, full of malevolent, cosmic forces, hiding something ancient and terrifying beneath its beauty.
