Chân Dung Hạt Thanh Thoát Của Nhà Thiên Văn

A 2x2 grid featuring ethereal data portraits of 4 famous astronomers: [Galileo Galilei, Nicolaus Copernicus, Johannes Kepler, Carl Sagan]. Each panel is styled as a scientific documentary poster set against an absolute pitch-black void. Each astronomer is depicted in a side-profile portrait looking upward, with their face and shoulders physically composed entirely of glowing, ethereal cosmic dust, bioluminescent particles, and electrical plasma. Crisp, thin gold and white vector line data overlays—featuring mathematical diagrams, planetary orbits, and celestial schematics specific to their discoveries—are layered over each subject. High contrast, with the glowing elemental particles illuminating the fine technical vector graphics.
