A first reference book for young astronomers curious about what's out there. Packed with updated photography and easy-to-follow text, this encyclopedia takes readers through the universe — from the very beginning of space to current space technology, astronaut life, nearby galaxies, and how to spot constellations in the night sky.

 Quizzes, at-home activities, and moon phase guides keep it interactive and hands-on. A great starting point for ages 6–8 who want real answers to big questions.
