Unbelievable, but true: this picture was taken with an ordinary digital camera, from a height of more than 20 kilometers. So how is this possible? There's a guy named Robert Harrison who did a simple job of filling a balloon with helium and tying a camera to it, programming it to take pictures every five minutes. Also, a rope and a small GPS transmitter were tied to the balloon, so that after landing, not to waste time looking for a camera. Having risen to a height of more than 20 kilometers, the balloon burst, and the camera landed safely on a parachute to the ground. As a result, the pictures received from the camera amazed everyone, including the NASA agency.
