'A mesmerising time-lapse video showing how Earth looks from space has been wowing the Web.
Nasa released the awe-inspiring footage which features a series of time-lapse sequences photographed by the Expedition 30 crew on board the International Space Station.
The clip, which plays to the haunting tune of ‘Walking in the Air’ by Howard Blake, begins over the southern United States at an altitude of 240 miles and finishes in Europe. Stunning imagery from the Aurora Australis over the Indian Ocean to lightning storms in Africa, shows the planet in all its glory. Heavily populated urban areas can be seen beautifully lit up in the dark of night.
The footage was put together using time-lapse photography, where the frequency at which the images are captured is much slower than that at which they are played back, giving the impression that the images are moving.'
