Voyager 1 Spacecraft Nears the Edge of the Solar System

Voyager 1, an unmanned probe that NASA launched into space in 1977 to study the outer planets in our solar system, is still doing remarkable things 30 years after it photographed Jupiter and Saturn. According to a Voyager Project scientist, new data from the probe indicate that it is nearing the boundaries of interstellar space, the space between stars where matter becomes even more sparse.

The pivotal moment in Voyager 1’s journey outside of our solar system is still to come, however; within about five years’ time, it is expected to cross over into the heliopause, the ‘official‘ edge of the solar system.
