Earthlings in perspective

The vastness of our universe is mind blowing. Even distances in our local "neighborhood" are huge. In an article about the federal government's long-term plans for space exploration, Talking Point Memo writes, "The solar system's nearest stellar neighbor, Alpha Centauri, sits 4.5 light years away. Voyager I, currently the farthest human-made object outside our solar system, will have to travel for another 50,000 years before it enters the neighborhood of the stars." It kinda puts the Earth, and us, into perspective.
