NASA’s Voyager 2 probe exited our solar system nearly a year ago, becoming the second spacecraft to ever enter interstellar space.
It followed six years behind its sister spacecraft, Voyager 1, which reached the limits of the solar system in 2012. But a plasma-measuring instrument on Voyager 1 had been damaged, so that probe could not gather crucial data about the transition from our solar system into interstellar space.
Voyager 2, which left the solar system with its instruments intact, completed the set of data. Scientists shared their findings for the first time on Monday, via five papers You do not have permission to view the full content of this post. Log in or register now.


The analyses indicate 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.
“Material from the solar bubble was leaking outside, upstream into the galaxy at distances up to a billion miles,” Tom Krimigis, a physicist who authored one of the papers, said in a call with reporters.
The new boundary layers suggest there are stages in the transition from our solar bubble to the space beyond that scientists did not previously understand.
