a strange ribbon of energy and particles during the edge of the solar system very first spotted by a NASA spacecraft generally seems to serve as a kind of "roadmap into the sky" for the interstellar magnetized field, scientists say.
By researching ground-based studies and in-space findings of solar power system's mystical energy ribbon, which was initially discovered by NASA's Interstellar Boundary Explorer (IBEX) in '09, scientists are mastering additional information concerning the conditions during the solar power system's side. The analysis in addition sheds light in to the sunshine's environment safeguards the solar system from high-energy cosmic rays. [Photos and photos from NASA's IBEX Spacecraft]
"The thing I usually have been trying to do would be to establish a clear connection involving the extremely high-energy cosmic rays we are witnessing [from the bottom] and exactly what IBEX is seeing, " learn leader Nathan Schwadron, a physicist on University of the latest Hampshire, told Space.com.
Formerly, maps from ground-based observatories revealed scientists that groups of cosmic rays — acutely high-energy particles that are derived from supernovas — are correlated with the IBEX ribbon. The ribbon is about perpendicular toward interstellar magnetic field while cosmic rays flow, an average of, across the interstellar magnetized area. (The particles by themselves are created from interactions between your solar power wind and interstellar matter.)
Inside longer term, Schwadron stated work like this helps boffins better realize more info on the boundary between our solar power system and interstellar room. This might be a spot that just one goal — NASA's Voyager 1 spacecraft — has reached thus far, and scientists know little about what that environment is like.

Travelling through the transition area
The sun's sphere of influence in solar system is known as the heliosphere. The sunlight's "solar wind" of high-energy particles moves inside the heliosphere and pushes back against high-energy cosmic rays while it began with interstellar space. The change zone between those two areas is named the heliosheath.
Listed here is in which a mystery occurs: Voyager 1's dimensions for the magnetic field through the edge of interstellar area program a starkly various course associated with magnetic field inferred inside IBEX ribbon, Schwadron said.
"At that point, you say to yourself what’s wrong? What could possibly be the problem? It appears as though we've good separate verification your IBEX ribbon is purchased by the interstellar magnetized industry, and now we realize Voyager 1 takes fairly great measurements, " Schwadron stated.
The few researches examining this matter, showing little consensus. An October paper co-authored by Schwadron in Astrophysical Journal Letters argued that Voyager 1 could be measuring interstellar plasma to arrive through magnetic field outlines, but may nevertheless be within the heliosheath itself. This appears in comparison to results from NASA and other technology teams saying Voyager 1 is definitively in interstellar space.
The scientists noted that Voyager 1 is getting its information "at a specific time and place", but IBEX's data is collected and averaged across vast distances, in order that could also induce discrepancies.
