Voyager 2


NASA's Voyager 2 probe exited our solar system nearly a year ago, becoming the second spacecraft to ever enter interstellar space. On Monday, Voyager 2 completed the set of data, which indicates that there are mysterious extra layers between our solar system's bubble and interstellar space. Voyager 2 detected solar winds — flows of charged gas particles that come from the sun — leaking from the solar system. Just beyond the solar system's edge, these solar winds interact with interstellar winds: gas, dust, and charged particles flowing through space from supernova explosions millions of years ago.

Now the new measurements from Voyager 2 indicate that the boundaries between our solar system and interstellar space may not be as simple as scientists once thought. The data indicates that there's a previously unknown boundary layer just beyond the heliopause. In that area, solar winds leak into space and interact with interstellar winds. The intensity of cosmic rays there was just 90% of their intensity farther out.
