Solar System Bigger Than Thought?

Voyager 1 was launched 35 years ago, and is still in communication with Earth.  Scientiists had thought Voyager would be headed into interstellar space by now, but data says it's still within the domain of the Sun.

The solar wind flows out from the Sun until it begins to interact with, curve along, and break down as it reaches the interstellar medium.  Voyager doesn't detect that happening yet, contrary to the predictions of humans.  Now, physicists are saying it might be another year before Voyager is finally beyond the influence of the Sun.
