Voyager travelling through new region at Solar System edge

摘要

In early December 2011, NASA reported that Voyager 1 had entered a new region between our Solar System and interstellar space. Data from Voyager show that in this new region the wind of charged particles streaming out from the Sun has calmed, with the Solar System's magnetic field piling up and higher-energy particles from inside the Solar System leaking out into interstellar space. Scientists interpret this area as "a stagnation region in the outermost layer of the bubble" around the Solar System, showing that what is outside is pushing back. They will soon be able to tell what the space between stars is really like.
