More than 40 years after launch, Voyager 1 is still making new discoveries. The latest achievement by the craft is the detection of a faint, plasma “hum,” indicating that there may be more activity in interstellar gas than previously thought.

Surely I'm not the only one thinking, "Wait wasn't there an SF movie that started with this scene"?
