In April and July 2014, the Sun emitted three jets of energetic particles into space, that were quite exceptional: the particle flows contained such high amounts of iron and helium-3, a rare variety of helium, as have been observed only few times before. Since these extraordinary events occurred on the backside of our star, they were not discovered immediately. A group of researchers headed by the Max Planck Institute for Solar System Research (MPS) and the Institute for Astrophysics of the University of Göttingen (Germany) present a comprehensive analysis now in the Astrophysical Journal.
