Colossal cosmic jellyfish drifting through glowing starry nebula

A colossal jellyfish drifts through a nebula of swirling cosmic dust and starlight. Its bioluminescent tendrils trail behind it, illuminating ancient, forgotten ruins suspended in the void. The ruins are of a civilization long gone, their architecture alien and organic. The overall mood is one of profound loneliness and cosmic wonder. The style is a highly detailed digital painting, with a touch of surrealism and a color palette dominated by deep blues, purples, and glowing whites, reminiscent of astronomical photography.
