It has been spotted on the space station Mir 200 miles above the earth.

This whole earth which we inhabit is but a point in space. How far apart, think you, dwell the two most distant inhabitants of yonder star, the breadth of whose disk cannot be appreciated by our instruments? Why should I feel lonely? Is not our planet in the Milky Way? This which you put seems to me not to be the most important question. What sort of space is that which separates a man from his fellows and makes him solitary? I have found that no exertion of the legs can bring two minds much nearer to one another.

When you see the Earth from space, you don't see any divisions of nation-states there. This may be the symbol of the new mythology to come; this is the country we will celebrate, and these are the people we are one with.

The views of the Earth are really beautiful. If you've ever seen a space IMAX movie, that's really what it looks like. I wish I'd had more time just to sit and look out the window with a map, but our science program kept us very busy in the lab most of the time.

The difference between an ant walking down the sidewalk and the International Space Station orbiting the Earth is about four orders of magnitude. I never really timed how fast an ant goes. Then I was thinking about a lot of the intractable contemporary conflicts that plague the world today.

It was like she dropped off the face of the earth.
