NASA has a couple of useful sites to help keep up to date with the deep space missions of Voyager 1 and Voyager 2, plus others.
Voyager 1 and 2 have gone further into space than any other object from Earth.
Current distance and status of the Voyagers:

NASA's 'Eyes on the Solar System' is a 3d visualization, real time view of these and many other missions around the solar system. Very cool.
