Originally said to be a Nasa Photo, enhanced composite satellite
image. This photo was taken via satellite, on a cloudless day. Note
how the lights are already on in Holland, Paris, and Barcelona,
and how it's still daylight in London, Lisbon, and Madrid. The sun
is still shining on the Straight of Gibraltar, and the Mediterranean
Ocean is already in darkness. In the middle of the Atlantic Ocean
you can see the Azores Islands; below them to the right, the Madeira
Islands; a bit below them the Canary Islands; further south, close
to the furthest western point of Africa, the Cape Verde Islands.
Note how the Sahara is huge and can be seen clearly both during
daytime and nighttime. It is obvious to me that the reason you can
see the nighttime view of the Sahara, is that the moon is lighting
it. To the left, on top, is Greenland, totally frozen.
I have received word that the above information is not true.
While this is a pretty photo it was not created by NASA.
I received the photo in about 2001, shortly after I started my homepage,
as an attachment to an e-mail.
At the bottom of the NASA page it says "By dissecting this image,
we've learned that it is composed of many elements, collected by
a variety of instruments, at different times and places, with several
wavelengths of light (and even sound) -- combined in a computer
to create an "impossible" view of the Earth. Scientists use images
like this -- called visualizations -- to interpret complex data,
and communicate their understanding to others. The image itself
was generated by the Earth and Moon Viewer, a Web-based tool that
produces Earth imagery from several perspectives. The Earth daylit
and night-time images were developed by The Living Earth"
