Voyager may exit our solar system much earlier sooner than expected

"NASA launched the Voyager 1 probe back in 1977 and sent it on its journey through our solar system to study planets as it passed on its way outside of our solar system. Back in December of 2011 NASA mentioned that Voyager 1 was entering into a new region of space, the stagnation region, which is sort of like a bubble around our solar system. This region is one of the last indicators that the probe is still within our solar system."
