Create a stunning digital art of a lone astronaut exploring an alien planet. The astronaut should be in a suit, holding a device or a weapon, with a panoramic view of the planet's terrain behind them. The scene should be set during the day, with vivid colors and bright lighting. The terrain should be full of intricate and highly detailed features, such as mountains, valleys, craters, and other natural formations. The atmosphere should be sci-fi, with elements such as spaceships, futuristic buildings, or advanced technology visible in the background. The style should be smooth and polished, with a touch of realism. Use art by Syd Mead, Simon Stålenhag, and Alex Ries as references for inspiration.
Avoid any depiction of violence, war, or destruction in the image. Do not include any humans or recognizable animals, such as dogs or cats. Do not use any heavy or oppressive colors, such as black or red. Avoid a gritty or dirty style. Do not include any supernatural or horror elements, such as ghosts, monsters, or zombies. Avoid any hint of a dystopian or apocalyptic setting.
