A professional and stunning YouTube thumbnail, 8K ultra-detailed, maximum quality, 16x detail level. The image should feature a unique, awe-inspiring cosmic entity that embodies the expanding universe. In the center, a majestic spiral galaxy acts as the core, with brilliant light trails and fast-moving stars radiating outwards in a dynamic, epic motion. The overall mood is grand and cinematic. The primary colors should be deep space blues, purples, and radiant gold. The design is artistic and visually epic, with a strong sense of infinite expansion.
