    An animation of a solar tsunami
    This visualization of a computer model simulation shows a solar tsunami, which is initiated at the equator. As the tsunami travels toward the poles it buoys the toroidal magnetic fields (white lines) traveling deeper in the solar interior. As these bands are lifted to the surface, they erupt as sunspots on the solar surface. (©UCAR. Visualization: Mausumi Dikpati, NCAR. This animation is freely available for media & nonprofit use.)

    The next solar cycle is predicted to take off within a year. In a pair of new papers, scientists paint a picture of how solar cycles suddenly die, potentially causing tsunamis of plasma to race through the Sun’s interior and trigger the birth of the next sunspot cycle only a few short weeks later.

    The new findings provide insight into the mysterious timing...
