Cosmos: Space Quiz for Kids turns astronomy for kids into an adventure. Children explore the solar system, planets, the Moon, stars and galaxies through colourful learning slides, then play a friendly space quiz to see what they remember. Every question comes with a simple explanation, so kids learn something new even when an answer is tricky.

A SPACE QUIZ FOR KIDS WHO LOVE TO LEARN Made for curious children aged 8–13, Cosmos blends space facts for kids with quick, rewarding quizzes. It's perfect for young astronomers, classroom science, or anyone who wants to learn about planets and the universe.

WHAT KIDS EXPLORE • The solar system and all eight planets • The Moon — its phases and eclipses • The Sun and the stars • Galaxies, black holes and the universe • Astronauts, rockets and space missions • Comets, asteroids and meteors • Constellations, telescopes and stargazing • How gravity, light and space really work

HOW IT WORKS Kids pick a topic, read through illustrated space slides, then take a quiz. Correct answers and honest "I don't know yet" answers both earn points — because trying and learning always count. Points become stars, collected on a constellation that lights up as kids progress.

SAFE, CALM AND AD-FREE No ads. No links out. No chat. No pressure timers. Kids never sign in and never share personal information. Parents can optionally back up progress behind a parental gate, and the learning slides are always free.

The full learning slides are always free for everyone. An optional one-time purchase unlocks the complete question set — no subscription.
