Horsehead Nebula Poster

Create a cinematic astrophotography-style educational space poster of the Horsehead Nebula, nebula_name, in a wide horizontal 4:3 canvas. The background is a deep red emission nebula filled with dense tiny white stars, with a glowing crimson hydrogen cloud band running horizontally through the middle. Center-right, place one large dark black-brown dust cloud silhouette shaped like a horse’s head and neck, rising upward with a curled snout and mane-like wisps, rim-lit by red light from behind. Add subtle blue haze in the lower-left corner and two especially prominent blue-white stars: one bright star near the left edge and one smaller bright star in the right-middle area, plus many smaller stars scattered naturally. In the upper-left corner, overlay exactly 3 text elements in white serif type: a large Japanese headline headline_text, a smaller English subtitle subtitle_text, and a four-line Japanese description description_text. Use elegant museum-planetarium typography, high contrast, realistic nebula detail, no borders, no logos, no extra labels.
