THE FIRE IN WHICH WE’LL BURN This image captured by the Solar Dynamics Observatory shows an M9-class solar flare erupting on the Sun’s northeastern hemisphere, just four days after a previous strong coronal mass ejection that sparked auroras around the world. A very fast coronal mass ejection travelling four million miles per hour (6.4 million kilometres per hour) is headed towards the Earth. (Photo: NASA / SDO via The Telegraph)
