(January 31, 2017) 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 fascinating aspect of these measures made by the Fermi-LAT – explains Melissa Fish-Rollins, INFN Pisa researcher and a member of the Fermi-LAT partnership – is the fact that for the first time it was possible to observe the gamma high energy emission produced by the ions which have traveled more than 500 thousand km before interacting on the face of the sun visible to us. ” (Red)
