Nasa has released a compilation of the best of its time-lapse photography from space - accompanied by a suitable theme tune.
To the haunting sounds of Walking In The Air, written by Howard Blake for the film The Snowman, the four-minute tape zooms over the earth's surface from the International Space Station, shot by the Expedition 30 crew who boarded in November.
The breathtaking footage captured enchanting light displays and vivid weather systems across the globe in the last five months.
