Nothing in this group is invented. The celestial objects are real catalogued bodies, the constellations are the 88 the IAU recognizes, and the missions, rockets, and astronauts are ones that actually flew. Each result comes with the context that makes it worth drawing -- what a moon orbits, why a mission mattered, when a star was named -- which is why these get used for classroom prompts and trivia as often as for worldbuilding.
Every result here is drawn using crypto.getRandomValues() -- the Web Crypto API's cryptographically secure randomness -- instead of Math.random(), so it's genuinely unpredictable, not just statistically random. Learn more.
