Our own Machine has been similarly threatened before, though we were far less reliant on communication technologies then. On September 1, 1859, a storm on the surface of our usually benevolent sun released an enormous megaflare, a particle stream that hurtled our way at four million miles per hour. The Carrington Event (named for Richard Carrington, who saw the flare first) cast green and copper curtains of aurora borealis as far south as Cuba. By one report, the aurorae lit up so brightly in the Rocky Mountains that miners were woken from their sleep and, at one a.m., believed it was morning. The effect would be gorgeous, to be sure.

If it doesn’t happen soon, it’ll happen eventually. Great Britain’s Royal Academy of Engineering has pegged the chance of a Carrington-type event within the next two centuries at about a 95 percent probability. Such an event almost took place in the summer of 2012, actually, and involved a particle stream larger than we imagine the original Carrington Event to have been. But it just missed the earth, shooting harmlessly over our heads (over the top of a STEREO spacecraft, actually). When we are hit, at any rate, we won’t be able to save ourselves with some missile defense system meant for meteors; no missile could halt the wraithlike progress of a megaflare.

KILLER SUN Once upon a time, people on Earth were electrocuted by a solar flare “If there is a solar flare or a nuclear war, a thousand cans of pickled turnips aren’t going to save you.” —SARAH LOTZ1 ACROSS THE WORLD, TELEGRAPH operators were electrocuted and, at low latitudes, a blood-red aurora borealis appeared, so bright a newspaper could be read by it at midnight.2 The Carrington event, named after amateur astronomer Richard Carrington, who from south of London noticed a flare on the sun at the same time that a magnetometer at Kew flew off-scale, changed forever our ideas about the sun.3 Before September 1, 1859, our local star was believed to influence the earth only through its gravity and of course the warming effect of sunlight.

The impact of the solar flare distorted the earth’s magnetic shield, so solar particles were no longer merely funnelled down at the poles but could reach anywhere on the planet. The collision of solar particles with atoms in the atmosphere caused those atoms to glow and create the aurora. 3.

A more serious concern is Coronal Mass Ejections (CMEs), which should more accurately be called “coronal magnetic eruptions.” First recognized in the 1970s, these are missile-like ejections into space of vast amounts of solar plasma and magnetic fields. We are talking about something of roughly the mass of Mount Everest hurled into space at five hundred times the speed of a passenger jet. The Carrington event—the most violent solar event ever recorded—is now recognized to have been a CME. In 1859 the world was not dependent on electrical technology, so the CME caused no serious harm to civilization. Contrast this with the situation today. Changes in the magnetic field across electrical power grids can induce currents big enough to melt equipment.

So much modern business depends on the Internet and other electronic communications, while our food supplies are strongly tied into the availability of electricity to keep things running and chilled. It would, at least in the short term, be like a return to the Dark Ages. Luckily, such catastrophic solar events don’t happen very often. The most recent recorded solar EMP that did make it to the Earth was the so-called Carrington event of 1859, named after British astronomer Richard Carrington, who witnessed the original flare on the Sun. Several powerful coronal mass ejections hit the Earth at pretty much the same time. Back then, of course, dependence on electrical devices was much lower than it is today, but the primitive electric telegraph lines of the time, sometimes called the Victorian Internet, had high currents induced in them, causing sparking, setting fire to some telegraph offices and bringing the whole network down.

If he was a grazer, and the grass was as short as all that, he could never have picked enough blades of it in his trunk in a working day to keep that great bulk going; and if he was (as he largely is) a browser, his mouth wouldn’t need to reach the ground, anyway. When he came to drinking water, he could have waded in, or knelt down—it would have been no more inconvenient than the giraffe’s straddle. Richard Carrington reports: ‘In Africa few rivers are sufficiently deep to cause so large an animal as an elephant to need to swim, and it is customary for the migrating herds to ford them. Sometimes the water will cover the animals completely; they will then walk across the river bed with only the tip of their trunks showing like periscopes above the surface.’

In the ­middle of September 1770, bright auroral displays appeared around the globe for nine consecutive nights, as streams of charged particles from a solar CME, guided by the Earth’s magnetic field, encountered atoms high in the atmosphere.4 Unlike almost all such displays, which last for only one or two nights, the 1770 auroras testify to an im­mense and long-­ lived solar outburst, perhaps one even more power­ful than the mighty solar CME that produced the better-­known “Carrington event” in September 1859. Named ­after the astronomer who actually saw the solar eruption that sent charged particles ­toward the Earth, the Carrington event generated auroral displays as far south as Cuba, some of which ­were so intense that many ­people believed their cities to be on fire. The flood of fast-­moving charged particles also disrupted telegraph communications (the “Victorian internet”) around the world.5 ­Today a Carrington-­like event would wreak havoc to the tune of $2 trillion (according to an estimate by the National Acad­emy of Sciences).

(The astronomer Courtney Dressing has remarked that if civilizations exist on planets like t­hese, the astronomers could live happily on one half, with every­one ­else on the other, beach-­y side.36) Also, the K2 spacecraft observed a flare from the star equal in energy output to the terrestrial Carrington event described in Chapter 12, which could pose serious danger to any of ­these civilizations. ­Because the TRAPPIST-1 observations extend over only a few years, in comparison with the centuries on Earth that recorded a single comparable event, its flare confirms astronomers’ knowledge that M stars often undergo extremely energetic outbursts that would threaten danger to life on any planets close to ­these stars.

‘And there was me thinking the signal was just disrupting the mobiles around here,’ Steve said. ‘If it were, we wouldn’t be taking this as seriously as we are. Now we need answers and we need them quickly.’ Graham tapped his fingers on his chin. ‘Could this all be down to some sort of solar flare activity on the scale of the Carrington Event back in 1859, which knocked out much of the telegraph network?’ ‘You know your history,’ Kiera replied. ‘I should hope so. Astronomy is my job after all.’ I managed to hold back a smile as Steve’s nose twitched. Kiera narrowed her gaze at Graham. ‘A major solar flare was our first assumption too.

There was the prospect of hackers, motivated by political aims or pure demonic mischief, unleashing a virus on the systems that controlled the national grid, taking out society’s entire technological infrastructure. There were the massive solar flares that occurred periodically and could just as easily do the same thing without need of human agency. He was fond of mentioning the so-called Carrington Event, a massive eruption on the surface of the sun that had occurred at the turn of the last century and caused the breakdown of electrical systems across the world. It wasn’t a big deal back then, of course, for the simple reason that we didn’t yet have much in the way of electrical systems, but how much worse would it be now, at a time when the wipeout of the grid would mean the near certain collapse of the complex structures undergirding our world?

And, there is an even bigger threat, in terms of likelihood of occurrence, and that is coronal mass ejection. Today’s modern economies and patterns of employment have created a world that is increasingly dependent on access to electric power grids, application satellites and other vital infrastructures vulnerable to a solar storm like the Carrington event that occurred in 1859. At that time the Carrington telegraph offices were lit on fire and the northern lights were seen as far south as Cuba and Hawaii. A repeat of this event today with trillions of ions traveling at a reasonable fraction of the speed of light would have blown out electrical transformers, crippled satellite networks, and disabled vital infrastructure across the planet.

We will navigate through the fog, and we will not have a blueprint. We must start now. We can’t wait until the hazard is so clear that we all agree—then it will be too late. We are in the throes of a sustainability crisis. One thing or another will take us out. It might be climate change, or a Carrington Event, or a nuclear exchange set in motion by wealth inequality, a refugee crisis, or revolution, to name just a few of the awfully real possibilities. We are hurtling toward destruction. We must, therefore, with full consciousness, embark on something dangerous. We must seek the next frontier: the event horizon, beyond which we cannot see, from which we cannot return, but through which may be our salvation.

Your scenario will only work if the CME is moving in a straight line from the Sun, but if it spirals in from a slight angle, as it can do, then an e.m. pulse would be much less effective.’ Deep down she felt the whole enterprise was futile. Defending Earth against a really powerful CME with electromagnetic pulses would be like standing in torrential rain and trying to stay dry under a cocktail-stick umbrella. The CME that caused the great solar storm of 1859 or the near miss of 2012, which – had it been ejected nine days earlier – would have met the Earth full on, frying the world’s electronics and bringing much of human civilization to a halt, would both, if they struck today, be catastrophic. With the magnetosphere in its current sorry state, civilization on Earth wouldn’t stand a chance.
