Scientists say that our sun is going into a turbulent phase of its weather cycle that will last about two and a half years:
Forecasters keep eye on looming 'Solar Max'At its angriest, the Sun can vomit forth tides of electromagnetic radiation and charged matter known as coronal mass ejections, or CMEs.
This shock wave may take several days to reach Earth. When it arrives, it compresses the planet's protective magnetic field, releasing energy visible in high latitudes as shimmering auroras -- the famous Northern Lights and Southern Lights.
But CMEs are not just pretty events.
They can unleash static discharges and geomagnetic storms that can disrupt or even knock out the electronics on which our urbanised, Internet-obsessed, data-saturated society depends.
