Tim Peake
The British astronaut, who returned to Earth in June after spending six months on the International Space Station, has chronicled his adventures in a new book which is aimed at readers of all ages.
"Hello, Is This Planet Earth?" is a collection of 150 images taken from the International Space Station orbiting Earth, accompanied by commentary from Peake himself.
Peake took the photos while part of the European Space Agency's six-month Principia Mission, where he conducted experiments in the International Space Station's weightless research laboratory.
The photos range from natural wonders like the northern lights to birdseye views of cities showing how humans have impacted the planet.
From Sicily to the Seychelles, here are some of the most striking images in the collection.
