Voyager I Enters Uncharted Space

NASA’s deep space probe, launched 34 years ago, is finally entering the far edges of our solar system, just before entering the rest of the Milky Way galaxy. The Guardian reports:

Scientists at the US space agency said the craft had gone into a region at the edge of the solar system, describing it as “a kind of cosmic purgatory”.

Ed Stone, Voyager project scientist at the California Institute of Technology in Pasadena, said: “Voyager tells us now that we’re in a stagnation region in the outermost layer of the bubble around our solar system … We shouldn’t have long to wait to find out what the space between stars is really like.”

Cosmic purgatory is such a gnarly phrase.
