픽셀 아트 우주에서 파란 고래를 타는 우주비행사

Create a pixel art image featuring a dark purple background representing outer space, dotted with small white stars. In the center, depict a white-suited astronaut riding a blue whale, as if on a surreal cosmic adventure. Use a limited retro color palette (e.g., dark purple, white, shades of blue, and black) to emphasize the pixel art style. Employ techniques like dithering for shading and anti-aliasing for smooth edges. Ensure the astronaut and whale are detailed with bold, blocky pixels, evoking a whimsical and surreal retro digital art aesthetic.
