Is the sun going dark? Latest Nasa images reveal TWO giant holes - one covering almost 10% of the solar surface | Daily Mail Online: "Nasa has spotted a  pair of huge 'holes' on the solar surface.

NASA’s Solar Dynamics Observatory, or SDO, captured this solar image on March 16, 2015, which clearly shows two dark patches, known as coronal holes.

The larger coronal hole of the two, near the southern pole, covers an estimated 6 to 8-percent of the total solar surface, 142 billion miles - making it one of the largest polar holes scientists have observed in decades."
