Voyager 1 leaving our Solar System?

According to NASA's Jet Propulsion Laboratory in Pasadena, California, the Voyager 1 spacecraft is on the edge of our solar system. This means that possibly sometime in the next few months to the next few years, the Voyager 1 spacecraft might cross into interstellar space. Data from the spacecraft, launched in 1977, indicates that the environment out there at about 11.1 billion miles (17.8 billion kilometers) is rapidly changing. According to Ed Stone, Voyager project scientist at the California Institute of Technology in Pasadena, "The latest data indicate that we are clearly in a new region where things are changing more quickly. It is very exciting. We are approaching the solar system's frontier."
