A great collection of thrilling and fantastic space photos taken by NASA.
This is a beautiful collection of photos taken by NASA in March 2010. Some pictures show places of the Earth seen from the space or the sky, some show the space itself…
Photos are clickable.
The pics were taken by NASA astronauts from the International Space Station. At first, the pics were not interesting because all of them were blurred, but techniques and devices evolved over the years and now, you can have beautiful clear photos.
One interesting thing is that Tokyo seen by night is rather green while other cities are more orange/yellow. In fact, the majority of the urban area in Tokyo has light green mercury vapour lamps instead of orange sodium vapour lamps.
You will see pictures by night of London, Madrid, Athens, Cairo, Seoul, Hong Kong, Tokyo, Los Angeles, Las Vegas and lots more.
Thanks to NASA and the Cassini spacecraft, we now have the opportunity to watch these remarkable images of Saturn.
Some time ago we couldn't even dream of doing that. 
Some amazing photos of the Earth made from space from the different satellites or astronaut missions. You can find all these pictures with its detailed descriptions on the site the Earth Observatory.
