A gigantic hole has opened up in the sun and spewed out a massive stream of radiation that’s now heading towards Earth.
This ‘solar storm’ is set to hit our planet on March 14, which is Wednesday this week.
Whilst it’s not strong enough to blast humanity back to the Stone Age, it could play havoc with the satellites which power the world’s communication networks.
‘A geomagnetic storm is a major disturbance of Earth’s magnetosphere that occurs when there is a very efficient exchange of energy from the solar wind into the space environment surrounding Earth,’ said the Space Weather Prediction Center.
‘The largest storms that result from these conditions are associated with solar coronal mass ejections (CMEs) where a billion tons or so of plasma from the sun, with its embedded magnetic field, arrives at Earth.’
The huge space squall coincides with the formation of ‘equinox cracks’ which form around the equinoxes on March 20 and September 23.
These are the moments when the the Earth and Sun line up so that day and night are of roughly equal duration.
But this also causes huge cracks to open up in the magnetic field which stay open for hours.
Whilst this isn’t necessarily dangerous, it does cause stunning aurora because it lets the sun’s radioactive ‘wind’ gush into the atmosphere.
