Voyager data may reveal trajectory of solar system

Nearly 30 years after launch, the two Voyager spacecraft are still operational and returning useful data. In their early years they produced some of the first close up images of the large outer planets. Now as the two vehicles, flying in slightly different directions, near the edge of the solar system, they are providing clues on the shape of heliosphere, and quite possibly, the direction of the solar system through local space.
