Greenland ice island captured in satellite images
Satellite images released by Nasa have captured the scale of the ice island that broke off the Petermann Glacier in northwestern Greenland on 5 August.
The image on the left was taken on 28 July and the image on the right was taken on 5 August.
The floating chunk of ice measures approximately 250 square kilometres (100 square miles).
According to Nasa's Earth Observatory, the glacier lost about one-quarter of its 70km-long floating ice shelf.
