After 41 Years, Voyager 2 Probe Has Left the Solar System

December 16, 2018

After 41 years traveling through the solar system, NASA’s Voyager 2 probe has entered interstellar space. That makes it the second human artifact to leave our home behind to drift between the stars. You might be thinking this already happened, but that’s because the first object out of the solar system was the other Voyager. They’re both in interstellar space now, but they had very different journeys.
