Astronaut Chris Hadfield depicts Earth's beauty from space

Canadian astronaut Chris Hadfield has published a book of photographs looking back at Earth from the ''unique and privileged'' vantage point of the International Space Station.

It depicts some of the highlights of the planet, including Mauritania's Sahara ''eye,'' and Venice and New York City by night.

He also told the BBC's Katty Kay how he felt about the historic but awkward comet landing of the robot probe Philae, which bounced twice before settling in the shadow of a cliff.
