Neil Armstrong and the Eagle lunar lander are reflected in Buzz Aldrin's visor in one of the most famous images taken during the July 1969 moon landing.

You can tell Apollo was faked because ... only two astronauts walked on the moon at a time, yet in photographs such as this one where both are visible, there is no sign of a camera. So who took the picture?

The fact of the matter is ... the cameras were mounted to the astronauts' chests, said astronomer Phil Plait, author of the award-winning blog Bad Astronomy and president of the James Randi Educational Foundation.

In the picture above, Plait notes, "you can see [Neil's] arms are sort of at his chest. That's where the camera is. He wasn't holding it up to his visor."
