Scientists observe first Sun-like magnetic cycle on another star

An international team of scientists led by the University of Göttingen has observed a Sun-like magnetic cycle on another star for the first time. The Sun's magnetic field drives the Sun's spots and flares and fuels the Solar wind – a torrent of material that streams off our star into space. The discovery is important not only for stellar physics, but also to understand and predict how the Sun affects the Earth and our technological society through its magnetic activity.
