Scientists discover ‘Terminator’ tsunamis on the Sun's surface
Our Sun is quite literally a hotbed of activity. Scientists are learning more about our star's solar cycle, in which its magnetic field flips and its north and south poles swap approximately every 11 years. Little is known about what causes this dramatic shift, although it does seem to be related to sunspot activity. A new set of research papers has laid out more about why solar cycles end and how the cycles can trigger a tsunami of hot plasma to cascade through the Sun's interior.
