I find this really cool. First human made object is finally moving into interstellar space, after 30+ years of travelling. What will it find there?
The cosmic purgatory is so-defined because it’s a kind of stagnation region on the cusp of the bubble that envelopes our solar system and the space beyond. Solar winds here are erratic and–for the first time–blowing back inward at Voyager. This stagnation layer was long theorized to be at the fringe of the solar system, but this is the first hard evidence of its existence out there.
Video above tells the history of the Voyager missions.
