skychart
Skychart is a planetarium and stargazing application for macOS that displays the night sky as seen from any location on Earth at any time. It helps users locate and identify stars, constellations, planets, deep-sky objects like galaxies and nebulae, and satellites. The app is used by amateur astronomers, educators, students, and casual observers for learning about astronomy, planning observing sessions, and tracking celestial events.
AI Recommendation
1 suggestionWe could not confirm whether a native Apple Silicon build of Skychart exists — the search results were empty and the app's visibility online appears limited. If you rely on this app, contact the developer directly to ask whether a native build is planned before macOS 28 ships in September 2028, since an Intel-only build will stop launching on that release. You still have over two years to resolve this, but it's worth checking sooner rather than later so you can plan your workflow. As alternatives with confirmed active development and native Apple Silicon support, consider Stellarium (free and open-source, widely used by educators and amateur astronomers) or SkySafari (from Simulation Curriculum, actively maintained and available on both macOS and iOS). You may also reach out to the Skychart developer via their website or repository to ask about their roadmap.
