Why there are no photographs of earth from space ?
How many do you expect to find? To show a full disc the spacecraft taking the image must be directly between the Earth and the Sun, and far enough away to get the whole disc in its field of view. How many spacecraft have been in that precise position to take pictures? Earth orbiting satellites are too close. Geosynchronus satellites could do it, but they’re not there for pictures. Anything going further away is off to take pictures of other things. Apollo 17 took a few on its way to the Moon. http://www.lpi.usra.edu/resources/apollo… Then there’s the Japanese Kaguya probes from earlier this year: http://www.jaxa.jp/press/2008/04/2008041… Other than a handful of cases of this particular alignment, you’re just not going to get a full disc shot. There are literally thousands of images of Earth taken from space
