Look up at the night sky, away from city lights, and watch as the stars appear. These pinpricks of light are giant balls of burning gas, millions and millions and millions of kilometres away. So far away that it takes the light thousands of years to reach us. This book, published in collaboration with the Natural History Museum, looks at stardust in space - the substance that made the planets, that built the Moon, the stars, the comets, the meteorites and the asteroids - and asks what this dust is and where its journey started.
