Yes, that is cool. But I think this might be cooler:
NASA's Voyager 1 Spacecraft Has Left Solar System
NASA's Voyager 1 spacecraft — the farthest-flung object created by human hands — has left the solar system forever, scientists say.
On Aug. 25, 2012, 35 years after the Voyager 1 mission launched, Earth's most distant spacecraft detected a sharp change in the intensity of fast-moving charged particles called cosmic rays, suggesting it had left the outermost reaches of the heliosphere marking the edge of the solar system.
"Within just a few days, the heliospheric intensity of trapped radiation decreased, and the cosmic ray intensity went up as you would expect if it exited the heliosphere," said Bill Webber, professor emeritus of astronomy at New Mexico State University in Las Cruces, in a statement.
