The two Voyager probes have been traveling through space for 40 years. Voyager 2 launched on August 20, 1977, and is now over ten billion miles from Earth, yet it is still sending signals back. When we try to picture the space probe leaving the solar system, we imagine the models we used in school that showed us where the planets are in relation to the Earth. But those models were not made to scale, because that wouldn’t be practical -they wouldn’t fit in a classroom. To give us a more realistic idea of what that distance really looks like, Vox set up their own scale model and made a video.
So, Voyager 2 was barely started on its journey when it passed Pluto. And it’s just now leaving the heliosphere. Cosmic. -via Digg
