Bioluminescent jellyfish

A colossal, bioluminescent jellyfish drifts through the inky blackness of deep space, its tendrils trailing nebulae and stardust. The creature is surrounded by distant, shimmering galaxies and the faint glow of a dying star. The scene is rendered in a highly detailed, photorealistic style with a touch of cosmic horror, reminiscent of H.R. Giger's biomechanical nightmares and the vast, awe-inspiring canvases of space art.
