Big questions about the universe (Usborne Publishing Ltd)

The questions in this book were curated by the staff at London's Royal Observatory, to address all the most common - and a few uncommon - things that children want to know about space. Planets, moons, exploration and even some 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?'.
