The questions in this book were curated by the staff at the Royal Observatory Greenwich, in London, to address all the most common - and a few uncommon - things that children want to know about the universe and about outer space. It covers a mixture of basic questions about planets, moons, human exploration and the origins of the universe, as well as tackling really BIG questions such as 'How do black holes work?', 'Is it worth going to space?' and 'What's going to happen at the end of time?'

Join two curious children and a robot programmed with all the answers as they guide readers through some of the most mind-boggling facts, and a refreshingly honest take on what things we simply don't know, and how to approach questions that don't have simple, straight answers.

Ideal for reading alone, but also an excellent place to generate classroom debate about the wonder of science and the value of space exploration.
