About this book

Have you ever looked up at the night sky and wondered where everything came from, or how scientists worked out ideas as huge as black holes or the Big Bang? This fascinating non-fiction book takes some of the biggest scientific concepts in the universe and makes them feel exciting and approachable by telling the human stories behind them. Across ten chapters, Dr Sheila Kanani explains each scientific idea clearly, showing how it works, why it matters and how it has changed the way people understand space, physics and the world around them.

There is a lovely sense of wonder throughout this book, helped by Liz Kay’s cool, graphic illustrations. The scientific content is well-pitched and engaging, covering brilliant thinkers, surprising accidents and questions that still puzzle scientists today. It also does a great job of showing that science is shaped by many different people and cultures, detailing the history of these groundbreaking discoveries in a broad and rich context.

A beautiful looking, immensely interesting fact-packed book that will spark curiosity, encourage big questions and help budding scientists see the universe as something they can explore, understand and keep wondering about.

About the author

Dr Sheila Kanani is a space cadet, with her head high up in the clouds, even though her feet are firmly on planet Earth. Sheila became interested in space and astronomy at the age of 13 and her passion sky-rocketed from there. She has a PhD in planetary science and her favourite planet is Saturn. Her favourite "work" interests are teaching GCSE astronomy and giving public talks to audiences of all ages and sizes, while representing her place of work, the Royal Astronomical Society, which she adores.

Outside of astronomy, Sheila loves to play hockey and the saxophone, enjoys listening to records and dancing like no one is watching with her husband and young son, and curling up on the sofa with an excellent book and her six-fingered cat. Sheila's love of writing began when she was nine and she started a daily journal, which she has kept (mostly) up to date ever since!
