Explanation:
No single spacecraft or astronaut took
this picture.
It is a digital composite of archived images
taken over many orbits by several Earth-orbiting satellites.
Similar images can be digitally stitched together for any Earth location by
John Walker's
Earth and Moon Viewer
website.
Specifically, the
daytime images were taken by the
MODIS instrument on NASA's
Terra satellite,
while the nighttime images were taken by the
DMSP satellites.
This image is
different from what an
astronaut would see for reasons
including a complete lack of clouds and an unrealistic exaggeration
of lights and contrasts.
The image has become both an
internet soliton in that it continues to circulate
as an attachment to digital correspondence, and a modern
urban legend.
Another image like that is
Earth at Night.
The reason for the image's continued popularity might be simple:
it is really cool looking.
