An illustration depicts a retro-inspired scene with a sleek alien spacecraft resting on the rocky surface of a distant exoplanet. Nearby, two astronauts in classic 70s-style space suits are exploring the terrain. In the distance, a colossal, swirling green gas giant dominates the sky, casting an ethereal glow over the landscape. The scene is bathed in vibrant hues, with a starry universe stretching infinitely behind, evoking a sense of wonder and adventure characteristic of vintage sci-fi artwork.
