How does the Hubble Telescope send it's photos to earth?
Photos are taken digitally on-board Hubble, stored on an internal computer and then downloaded to earth based computers over a wireless data link. Slower but similar in some ways to WiFi data used by laptops, or data transmissions used by digital cell phones.

The only ways to see that side are: -- Send a robotic spacecraft to orbit the moon. Have it photograph the back side when it's there, and then send those photos to Earth when it comes back around to our side. -- Send people in a spacecraft to orbit the…
