    Enigmatic "Ribbon" Of Energy Discovered by NASA Satellite Explained
    February 5, 2013 - DURHAM, N.H. -- After three years of puzzling over a striking "ribbon" of energy and particles discovered by NASA's Interstellar Boundary Explorer (IBEX) at the edge of our solar system, scientists may be on the verge of cracking the mystery. In a paper published Feb. 4, 2013, in the Astrophysical Journal, researchers, including lead author Nathan Schwadron of the University of New Hampshire, propose a "retention theory" that for the first time explains all the key observations of this astrophysical enigma. "If the theory is correct," Schwadron notes, "the ribbon can be used to tell us how we're moving through the magnetic fields of the interstellar medium and how those magnetic fields then influence our space environment." In particular, these strong magnetic fields appear to play a critical role in shaping our heliosphere - the huge bubble that surrounds our solar system and shields us from much of harmful galactic cosmic radiation that fills the galaxy. This may have important ramifications for the history and future of radiation in space, and its impact here on Earth, as the heliosphere changes in response to changing conditions in the interstellar medium or the "space between the stars."

    According to the retention theory, the ribbon exists in a special location where neutral hydrogen atoms from the solar wind move across the local galactic magnetic field. Neutral atoms are not affected by magnetic fields, but when their electrons get stripped away they become charged ions and begin to gyrate rapidly around magnetic field lines. That rapid rotation creates waves or vibrations in the magnetic field, and the charged ions then become trapped by the waves. This is the process that creates the ribbon. "Think of the ribbon as a harbor and the solar wind particles it contains as boats. The boats can be trapped in the harbor if the ocean waves outside it are powerful enough. This is the nature of the new ribbon model. The ribbon is a region where particles, originally from the solar wind, become trapped or 'retained' due to intense waves and vibrations in the magnetic field."

    This "ribbon" of energy that is well documented and is getting closer and will eventually pass right by/through our system. The ribbon has now streamed way deep into our solar system. Streams of hot plasma has already reached Jupiter and that is the cause for the recent explosions in Jupiter.
