Create an ultra-wide cinematic alien planet landscape titled by mood rather than text, with no spaceship and no city, only an impossible cosmic horizon. The scene shows a vast jagged valley of dark crystalline mountains under a spectacular star-filled sky. Include exactly 5 prominent mountain spires: one huge black serrated spire dominating the far left foreground, one smaller sharp spire near the center-left distance, one tiny glowing central horizon peak, one large jagged ridge-spire on the right midground, and one distant far-right peak. A luminous icy-blue river or energy stream winds from the foreground center into the glowing horizon, reflecting starlight across misty terrain. Above the horizon, place 1 enormous tilted spiral galaxy with a bright warm white-orange core on the upper left, stretching diagonally across the sky with purple, pink, blue, and gold nebula clouds. On the upper right, place exactly 1 giant ringed gas planet with pastel violet, mauve, and indigo bands, plus exactly 3 moons around it: one small moon above-left of the planet, one smaller moon left of the planet, and one larger gray moon overlapping near the lower-right edge of the planet. Add crystalline blue-purple rocks in the right foreground, glowing faintly like embedded stardust. Use {argument name="color palette" default="deep indigo, violet, magenta, electric blue, warm gold, and icy cyan"}, {argument name="planet mood" default="mysterious and awe-inspiring"}, and {argument name="horizon glow" default="soft golden sunrise-like radiance"}. The style should be epic high-detail fantasy space art, photorealistic digital painting, dramatic scale, sharp foreground detail, atmospheric mist, rich nebula texture, volumetric light, high contrast, 16:9 panoramic composition, no text, no watermark, no people, no buildings.
