It's perched on the very edge of the solar system, and new data is the strangest yet
For at least a year now, NASA has been waiting with bated breath for Voyager 1 to pass through the boundary of our solar system and become our first emissary to the stars. It’s been cruising the edge for some time, but when it finally leaves forever, it won’t be a satisfyingly clear punch-through — so it’s hard to say exactly when this will happen. Or happened. Now the spacecraft is in another strange new zone, where the influx of cosmic particles has been ramping up by the week.
