Astronaut in an Oasis: Photorealistic Encounter

Photorealistic image of an astronaut in a pristine white spacesuit standing at the edge of a shimmering turquoise oasis on an alien desert planet. The pool is ringed with lush palm trees; warm late-afternoon sun casts golden reflections on the water and long shadows across the sand. The helmet visor reflects the oasis and distant dune fields. The suit bears colored patches, a tether line, and a compact oxygen backpack. Footprints lead to the water and fine sand grains cling to the boots. A light breeze rustles the palm fronds, and subtle lens flare adds realism to the scene.
