What are stars? is the third in the Very First Questions & Answers series, following on from What is poo? and What are germs? It explores how stars aren't just the pointy shapes we know - in fact the tiny twinkly stars in the night sky aren't star-shaped at all and they aren't tiny. They're actually massive burning balls. The book goes on to explain how stars make patterns in the sky, how the Sun is our nearest star, and how shooting stars aren't stars but whizzing lumps of space rock. Charmingly illustrated by Marta Alvarez-Miguens, each page has flaps to lift and find out more.
