Cascade cosmique d’une galaxie tourbillonnante se déversant dans une rivière lumineuse

A colossal waterfall cascading from a towering cliff, but instead of water, it pours with liquid galaxy—an endless stream of swirling cosmic colors. Shades of deep violet, electric blue, nebula pink, and shimmering stardust tumble over the edge like flowing stars. At the base, the waterfall crashes into a wide, rushing river made entirely of the same glowing galactic substance. The river churns with luminous energy, reflecting constellations as it winds through an otherworldly landscape. The scene feels vast, surreal, and awe-inspiring, blending the majesty of nature with the wonder of the cosmos.
