Could you build this?
Partial Public star and galaxy catalogs exist, so the app is buildable, but rendering hundreds of thousands of objects smoothly across scales with level-of-detail needs graphics optimization beyond typical vibe-coded output.
What it would actually take: The stack would be a native iOS app using Metal or SceneKit, with a preprocessing pipeline that converts catalogs such as Gaia and galaxy surveys into spatially indexed, level-of-detail chunks. The hard part is smooth rendering and seamless zoom from solar-system to cosmic scales, which requires graphics and astronomy-data expertise to get right.
