Three Vast 'Holes' Just Appeared on the Sun—and They're Bombarding Earth with Geomagnetic Storms

Three vast “holes” have opened up on the Sun over the past week, according to NASA’s Solar Dynamics Observatory (SDO), allowing high-speed solar winds to escape into space and bombard the Earth. The holes spew out charged particles which can affect animals and electronic systems on Earth, and cause auroras to appear at lower latitudes than normal if they interact with the magnetosphere—the region around our planet dominated by its magnetic field.
