a digital art composition of an astronaut standing in the center of a cathedral interior. the astronaut wears a white and gray space suit with black harnesses and straps, and a reflective gold visor helmet. the cathedral features gothic architecture with pointed arches, stone columns, and tall stained glass windows on the right wall. the floor is polished and reflective, creating colorful light patterns from the stained glass windows. the lighting is dramatic, with warm candlelight illuminating the left side of the space, contrasting with the cool, ethereal light from the stained glass windows. the color palette includes deep blues, greens, and reds from the stained glass, reflecting on the wet floor. the perspective is centered, with the curved arches leading the eye to the vanishing point. the overall atmosphere is mystical and otherworldly, blending religious architecture with space exploration. the image has a cinematic quality with professional lighting and composition.
