If you like jigsaws, you’d love to be on the team at the European Space Agency that created this image. Made up of 7,000 separate files — totalling 32 terabytes of data — the picture provides a completely cloud-free view of the whole of Africa.
Each of the vaguely vertical strips in the image was collected by the ESA’s Sentinel-2A satellite and measures 180 miles wide. The majority of the images were collected between December 2015 and April 2016. And the space agency is pretty proud of the feat: it says that “being able to capture the Tropics cloud-free over the five months is remarkable”. [ESA]
