NEBULA is an astronomy quiz you can race or author yourself. Chain correct answers to build a streak multiplier, then download a polished canvas scorecard stamped with your rank (Interstellar Genius → Space Tourist) and share it. Build your own question set, or take the curated 10-question orbit.
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.
