'Surprises' in the outer solar system
A few of us geezers still remember the day in 1977 when Voyager 1 began its decades-long mission to Jupiter and Saturn. Today, according to this NASA post, the spacecraft is still going strong 30 years later and has encountered some "surprises from the edge of the solar system."
Among them: "magnetic potholes," "sluggish solar wind" and "anomalous cosmic rays." If there's a quiz in the morning, we're sleeping in.
