So Voyager 1 is 1/6 of the way to the Sun's gravitational lens focus, a point in space past which the Sun itself acts as a gravitational lens (with a very small field of view) in the opposite direction. Those points can be exploited by space telescopes for direct imaging of extrasolar systems and for interstellar communication.
