Tim Peake was the first British astronaut to conduct a spacewalk at the International Space Station, and an inspiration for budding young scientists and astronauts everywhere. In this out-of-this-world event, Peake talks about his first non-fiction book for children, The Cosmic Diary of Our Incredible Universe, in which readers will discover everything from how stars are made, to which fruit can create antimatter. Peake is a former Apache pilot, flight instructor, test pilot and European Space Agency astronaut whose books include his memoir Limitless, and the photography collection Hello, is this Planet Earth?
