NoctoSky
A real-time planetarium for the whole sky
NoctoSky is a real-time 3D night sky you can fly through from your browser — 3.9M stars, 10K+ galaxies, clusters and nebulae, confirmed exoplanets, and live spacecraft positions from JPL Horizons. Ask the AI guide anything and it flies the camera straight there. Rewind or fast-forward time to any night, past or future. Track active space missions live. Built solo, free, ad-free. Just point and explore your destiny written in stars.

Hey Product Hunt! 👋 I'm Pavel, and I built NoctoSky solo — it's a real-time, explorable 3D night sky right in your browser. The idea started simple: I wanted to look up at the sky, ask "what's that?", and actually get an answer — without downloading a heavy planetarium app or digging through forums. So NoctoSky ties together the same catalogs professional astronomers use — Tycho-2 (3.9M stars), OpenNGC (10K+ galaxies, clusters, nebulae), NASA's exoplanet archive, and live spacecraft positions from JPL Horizons — into one map you can just fly around. A few things I'm proud of: 🔭 Ask the AI guide anything ("show me the Orion Nebula") and it flies the camera straight there ⏪ A time machine — rewind or fast-forward to any night, past or future 🛰️ Live Missions — track active probes against real orbital data 🌍 Works from wherever you are on Earth, no login needed It's free, ad-free, and a genuine one-person passion project — no team, no funding, just me and a lot of late nights. I read every piece of feedback personally, so if something looks wrong, feels clunky, or you just want to say hi — I'd love to hear it here. Thanks for checking it out! 🌌
