Voyager 2

At https://phys.org/news/2019-11-voyager-interstellar-space-scientists-plas… … interstellar space – scientists detect plasma density jump as Voyager 2 moved from the solar system to beyond. The inference is that outer space has a higher density level of plasma – or that is the thinking of researchers in a paper in Nature Astronomy (Nov 2019) – although one might argue it is the bubble around the solar system that is dense (I suppose). There is definitely a boundary at the outer reaches of the solar system – as experienced somewhat earlier when Voyager 1 passed through. The boundary is approximately 11 billion miles away from the Sun.
