Check out this incredible picture of Earth. You'd think it was taken using special equipment like a satellite wouldn't you? We did...

Well we were all wrong. These were taken by an ordinary man with three kids. He used a large balloon, a camera and a computer!

Robert Harrison from West Yorkshire started his project in 2008. He wraps up a camera in loft insulation and attaches it to a weather balloon.

He sends the balloon up about 22 miles into the sky. And he uses a computer to trigger the camera every five minutes. And these are some of the images that come back!

His photos are so amazing that space agency Nasa contacted him to ask him how he did it. Their satellites cost millions of pounds.

But Robert's equipment costs just 500. He said his family and friends thought he was a "bit mad" at first, but then they saw his pictures and were impressed.

Once the balloon reaches 22 miles up, it bursts and a little parachute gets released. Robert then tracks where it lands by using a sat nav.
