NASA satellite Voyager 1, at 36 years young, is the first manmade object in recorded history to enter interstellar space. Moreover, it's apparently been doing so for around one year -- NASA scientists at the Jet Propulsion Laboratory announced as much this afternoon, and explained how they were tipped off. "We have an instrument on board which can measure the density of ions, the plasma which is out there," Voyager project scientist Ed Stone said in a prepared video.
