The Earth is a truly beautiful and fascinating place – even more so when seen from Space as distances and proportions take on a whole new dimension. Is this how ants see their world, we wonder? Follow us on a tour of our Blue Planet as seen from Space and be ready for some stunning pictures.
Let’s begin our tour of the Earth from Space by looking at the Earth at night:

This is a composite picture taken at various times during the night that was then pasted together to create the appearance of Earth at night. Or did you think it is night all over the world at the same time?
Amazing how bright and clearly visible some of the urban areas are. Let’s take a closer look.
Here are the Americas at night:

And Europe, Africa and the Middle East:

Asia and Australia:

Not to miss Antarctica, here’s a beautiful and rare full view of the seventh continent:

Staying with the winter mood, below is an image of Scandinavia in winter – truly a pretty one. One can clearly make out the many fjords, etched into the Norwegian coastline. Lake Vänern and Lake Vättern in Sweden do not completely freeze in winter, whereas Finland’s many lakes are too small to be clearly seen from Space.
A winter wonderland – snow-covered Scandinavia:

Speaking of snow and ice, here’s Greenland’s eastern coast with inland snow slowly making its way to the coastal lands while the fjords are bordered by the icy waters from the sea.
Greenland’s coast just before the onset of winter:

Another extreme climate zone is the Saharan desert. Its vastness seems graspable only from Space:

Islands are a popular photographic motif with astronauts who snap them again and again. Maybe it’s because they are clearly marked, self-contained entities, similar to a spaceship. Here’s a selection of a few islands that caught our eye.
At more than 2,000 miles from the closest populations on Tahiti and Chile, Easter Island is one of the most remote places on Earth. Even the astronauts orbiting were closer: only 210 miles above.
Easter Island:

Hawaii, looking somewhat like a pancake with a dash of powdered sugar:

And further east, Bahrain, the island country in the Persian Gulf:

Ireland, looking truly green and somewhat like a bear’s paw:

Cyprus, the Eurasian island state, with Turkey just above:
