# Four universe scenes: astronomical originals and generated panoramas

Since 0.4.0 the default **高清实景** mode displays the credited publication JPEGs directly, without image enhancement or upscaling. **艺术全景** retains the generated composites below. All images are embedded at build time; no network fetch is required during flight. The animated journey and particle effects are fictional visualization, not astronomical simulation.

| Original photograph | Included file | Actual dimensions |

Each original uses the same full credit and source link as its corresponding composite listed below.

These four WebP images are fictional astronomical artworks created for **yunxiang** with built-in OpenAI Image Gen on 16 September 2026, using the user-supplied reference pictures and the official images listed below. They are not telescope observations or accurate sky maps.
