Stylized black and white posterized illustration of a supernova-like spherical energy core in space. A bright, clearly defined sphere at the center, slightly rotated in perspective (not perfectly flat front view). The sphere has subtle volume and depth. From the sphere, two gas jets emerge in opposite directions, but slightly angled (not perfectly horizontal), giving a dynamic, tilted composition. The jets are thick, flowing, and organic, like plasma streams, not sharp lines. The gas is semi-detailed, with visible structure and motion, not too minimal, but still clean and stylized. NO explosion spikes, NO radial starburst, NO chaotic fragments. Color palette strictly monochrome (black, white, 1-2 gray tones). Strong posterization with visible tonal separation, but preserving some soft transitions for depth. Cinematic lighting, high contrast, slightly volumetric look. Below the image: text "NOVA" in bold futuristic font (Orbitron / Bebas Neue style), all caps, wide letter spacing. Centered but slightly dynamic composition, modern sci-fi aesthetic, not flat minimalism, more detailed but still graphic and clean.
