New Photo of Earth Unveiled

As humans debate the science and politics of the environmental impact on our planet, we may sometimes forget to stand back - say, from about 700 kilometres away - and admire the neighbourhood we live in. Scientists at NASA have released these photos of Earth, showing what they say are the truest colour images of our glorious globe ever captured. Using the Terra satellite, circling high above us, astronomers assembled thousands of images shot over months by the remote sensing device MODIS. Every patch of earth and splash of water was photographed for the mosaic, dubbed the Blue Marble series. Even global city lights were superimposed on the land surface. And if you look very closely, it looks like you left an upstairs window open in your place. For more from the series click here.
