“Concentrate all your thoughts upon the work at hand. The sun’s rays do not burn until brought to a focus.” –Alexander Graham Bell
The Sun, contrary to what you might normally think about it, isn’t a constant, uniform source of radiation. It has an active surface, replete with temperature variations, sunspots, and occasionally a large flare or mass ejection.
But on very rare occasion, a flare like this makes it way through space and just happens to make its way towards Earth, where this hot, fast-moving ionized plasma collides with us. While the aurorae it produces can be spectacular, some of the other unwanted effects can be catastrophic!
What will it means if we get hit by a big one? Find out the truth — separated from sensationalism and fear — here!
