太空探索：星际漫游特展

A cinematic exhibition poster for an interstellar space journey, centered grid layout with a colossal silver rocket blasting upward from the lower third, trailing an orange-gold exhaust plume and smoke, a ringed planet, orbiting moons and a violet-nebula sky filling the upper half, distant stars and tiny spacecraft silhouettes for scale. Bold condensed geometric sans-serif headline in luminous white reads 'STELLAR VOYAGE', set with wide tracking, thin uppercase sub-lines listing dates and venue, small starfield texture behind the type. Deep indigo, violet, teal and warm orange color system with high contrast. Matte art paper printed in offset lithography, subtle paper grain and one spot-varnish gloss band across the rocket. The poster hangs on a dark concrete gallery wall near a small pendant lamp. Soft warm spotlight from the upper left at evening-dusk quality wraps the paper edge and casts a soft shadow down-right. Wide shot, eye-level straight-on view of the full poster, all type and textures tack-sharp, 4k
