   The distance is something of the order of 5.7x10^9 km; dividing by the speed   
   of light (about 3x10^5km/s) then gives us (about) 1.6x10^4 seconds, or about   
   44 and 1/2 hours.   
      
   Incidentally (and this may sound pedantic but it's not) it is an image, not   
   a photo. The image is scanned, and transmitted, pixel by pixel, line by   
   line, not taken as a snapshot.   
      
   Cheers.
