What is a black hole? How do we know that stars and galaxies are billions of years old? What is the difference between stars and planets? Glenn Murphy, author of Why is Snot Green?, answers these and a lot of other brilliant questions in this funny and informative book. Packed with doodles and information about all sorts of incredible things, like supermassive black holes, galaxies, telescopes, planets, solar flares, constellations, eclipses and red dwarfs, this book contains absolutely no boring bits!
Glenn Murphy wrote his first book, Why Is Snot Green?, while working at the Science Museum, London. Since then he has written around twenty popular science titles aimed at kids and teens, including the bestselling How Loud Can You Burp? and A Kids' Guide to Global Warming. His books are read by brainy children, parents and teachers worldwide, and have been translated into Dutch, German, Spanish, Turkish, Finnish, Chinese, Japanese, Korean and Indonesian. Which is kind of awesome. In 2007 he moved to the United States and began writing full-time, which explains why he now says things like 'kind of awesome'. These days he lives in sunny, leafy North Carolina - with his wife Heather, his son Sean, and two unfeasibly large felines.
