A lone astronaut in a vibrant orange spacesuit stands waist-deep in a dark, flowing river. The scene is shrouded in a mysterious, ethereal blue light. The astronaut is holding a luminous, translucent sphere that casts a soft, otherworldly glow on the water. Rocks and sparse vegetation line the riverbank, painted in muted greens and grays. The water's surface reflects the cosmos above, a myriad of tiny, twinkling stars. The astronaut's visor reflects the swirling colors of distant galaxies. The composition emphasizes the vastness of space against the intimacy of the river, creating a dreamlike, contemplative atmosphere. Rendered in a style reminiscent of impressionistic science fiction art, capturing the emotional depth of exploration and the unknown, highly detailed, 8k, hyperrealistic.
