NASA has released an impressive 'Blue Marble' image of the earth taken from the VIRS instrument on the Suomi MPP satelitte.
Taken in early January, the image is a high-definition composite picture of the earth which dramatically builds upon the classic 1972 Blue Marble satellite image, from which the new picture takes its name.
