Cosmoscope turns 20 curated astronomy questions into a quick, beautiful cosmic quiz. Answer, learn the fact behind every response, chase your best streak and best-of-run score, then earn a shareable canvas-drawn "cosmic certificate" you can download or share. A polished no-build HTML/CSS/JS app with a live twinkling starfield and a portrait + landscape-ready touch-first interface.
An interactive gravity sandbox that answers one question: can a passing star destroy the whole solar system? Aim a star at the Sun, tune its mass, miss distance and speed, then watch a real symplectic N-body simulation decide the fate of all eight planets — with a live "reality check" on how often such encounters actually happen.
