What's Visible from Outer Space

By October 8, 2003

Follow me on:

You may have heard it said that the Great Wall of China is the only man-made object visible to the naked eye from outer space. Not true. As a matter of fact, astronaut Ed Lu told Space.com recently, a great many human artifacts can be seen on earth from space — cities, airports, roads dams, ships, the Great Wall and the pyramids of egypt — and he's got digital photographs to prove it.

My history teacher literally *just* told us that the great wall is the only artifact that can be seen from space.

Good day! I know this is somewhat off topic but I was wondering
if you knew where I could get a captcha plugin for my comment form?
I’m using the same blog platform as yours and I’m having difficulty finding one?
Thanks a lot!
