Astronaut Gardening in an Alien Biodome

A lone astronaut tending to a small, vibrant garden growing inside a biodome on a barren, red-hued alien planet. The distant Earth is visible as a small blue marble in the dark, star-filled sky. The astronaut pauses, looking at a single blooming flower with a look of quiet satisfaction. This is depicted in a highly detailed, realistic digital painting style with cinematic lighting, inspired by the space art of Chesley Bonestell and the atmospheric sci-fi concepts of John Harris. A sense of hopeful isolation.
