This is Juruá River snaking through the Amazon rainforest in western Brazil, from the Envisat satellite. Along the river’s main course are free-standing ‘oxbow lakes’, formed when a river changes course. Image credit ESA
This image is a compilation of three images from Envisat’s radar, acquired on 2 January, 1 February and 3 March 2012. The individual images are each assigned a colour – red, green and blue – and when combined, reveal changes in the surface between Envisat’s passes.
