This year, British astronaut Tim Peake took up his six-month post in the International Space Station. During his time there, the world watched as he opened the London Marathon chained to a treadmill, was chased by a gorilla and tweeted pictures from beyond the Earth's atmosphere.
There may be no more astonishing and grounding way to see the world; he described our planet as "a stunning oasis of life in the vastness of space."
Now, his photos feature in Hello, Is This Planet Earth?, a gorgeous coffee-table book full of his best stories of time in space and reflections on Earth. Here are 21 of our favourites.
