Don’t give up just yet. There is still hope for humanity. If you thought Mankind had descended into a baying horde of tax-dodging, Edexcel-colluding, The-Only-Way-Is-Essex-watching looters, bankers and phone-hackers, think again. Through the gloom shines a ray of hope that is green and fuzzy and arriving from the most unexpected direction.
It all began last week with a CME - a "coronal mass ejection". A massive solar storm flung an enormous lump of material out of the sun and into space, hurtling towards Earth at around a million miles per hour. This kind of event has long been expected, because the Sun gets restless every 11 years, and is due to do so again this year and next. In fact, the harbingers of doom have been wringing their hands in glee at the calamity promised by a large CME. When it hits the Earth, it threatens to overload power grids and burn out the electronic technology on which we have become so reliant.
On Sunday, after travelling through space for three days, the dreadful lump of solar plasma finally arrived but, guess what, civilization did not end. There was no calamity. In fact, it turned out to be a thing of beauty.
As anticipated, the myriad electrons and protons, arriving from the Sun, spiraled round and round the magnetic field lines that extend out of the Earth’s poles like iron filings on a bar magnet. And, as anticipated, the planet’s magnetic field flexed and wobbled under the assault, making it sweep past power lines, creating a makeshift dynamo. Electrical current surged through the grid but the four horsemen of the apocalypse failed to show up. The electrical surges were relatively small, and the marvellous people in charge of the world’s power supplies coped admirably.
So, did those subatomic particles from space go unnoticed by the general population? Not at all. Never has a solar flare caused such commotion here on Earth. Our magnetic field funnelled the swarm of high-energy particles toward the poles, where they smashed into the upper atmosphere, making its oxygen atoms shine with an unearthly green light: the aurora. It’s not uncommon for polar explorers and reindeer to see the northern and southern lights, but this week’s aurora were big - so big that they extended down all the way to parts of the
UK, and mainland Europe.
But who cares about the aurora borealis? You and I do, but we’re special, aren’t we. For one thing, we love to marvel at the wonders of nature. Looking out into the clear night sky, and taking in the unbelievably vast majesty of it all gives us an overwhelming sense of exhilaration, that would only be increased by the excitement of witnessing the aurora. More than this, unlike the hoi polloi, we thoughtful types appreciate real beauty wherever it appears. Well...
Anyone tweeting during the last week knows that you and I are not alone in caring about the wonderful, mysterious, beautiful workings of the universe. On Sunday, and again on Tuesday when a second CME hit the Earth, Twitter was abuzz with excitement - not over the threatened electrical disaster - but over the impending aurora. People were re-tweeting the latest space weather predictions and everyone was hoping the lights would reach their local sky. First we got jealous of the Scandinavian tweeters, then Shetlanders reported miraculous skies, and soon even the coast of
was alight. And across the world, we shared their joy and excitement. A surprising number of sky-watchers are expert photographers, who managed to capture some of the celestial awesomeness, even in the challenging low-light conditions, and they very swiftly uploaded their wonderful pictures for the rest of us to marvel at. Thank you aurora watchers, for sharing your anticipation, your excitement and your amazing pictures. You have restored my faith in humanity. county Durham
In the end, the dancing green light shone on many happy appreciative people, but didn’t quite reach my
Yorkshire sky. I missed the live show, but I witnessed something equally beautiful and unexpected, on a social networking site.
