Washington – Fermi, the NASA satellite that studies gamma photons in space, which Italy participates with INFN, the National Institute for Astrophysics (INAF) and the Italian Space Agency (ASI), has revealed for the first time high energy solar flares, which originated in the face of the Sun not visible to us. The light that comes from these violent eruptions in the side hidden from us of the star should be blocked without coming to us. Instead, scientists from the Fermi collaboration were able to observe it because the ions produced and accelerated during flares, being electrically charged, they travel along the sun’s magnetic field lines, which connect the place where the blast took place with even distant parts of the sun.. The observations were made on October 11, 2013 and January 6 and September 1, 2014. The results of the three btl seen with Fermi-LAT were presented yesterday during the conference of the Americal Physical Society (APS) in Washington and published today in The Astrophysical Journal.
