Sun-Grazing Comets As Triggers For Electromagnetic Armageddon

Large sun-grazing comets could bring on the sort of global electronics meltdown usually associated with electromagnetic pulse weapons or a full-scale nuclear exchange.

Or so says David Eichler, lead author of a forthcoming Astrophysical Journal Letters paper positing that a sun-grazing comet roughly the size of Hale-Bopp (with a nucleus some 30 kms in diameter), could trigger cosmic ray-generating shockwaves large enough to initiate a global electromagnetic Armageddon.

Eichler, an astrophysicist at Israel’s Ben-Gurion University of the Negev in Beer-Sheva, argues that satellites that weren’t in protection mode would be wiped out along with most of the world’s electronics — everything from micro-circuitry on cell phones to full-scale power stations.

If such a comet were the size of Hale-Bopp, Eichler says, the resulting solar flare would by far be the largest ever observed.

The comet gets compressed and then explodes in the solar atmosphere which, in turn, creates shockwaves, says Eichler.

Eichler thinks that such a sun-grazing comet may have triggered a large solar flare and cosmic ray-generating shockwaves as recently as 775 A.D., as indicated by tree ring analysis pointing to a sudden 1.2 percent spike in atmospheric Carbon 14.

“I’m not saying that [event] couldn’t have been caused by a magnetic solar flare, but we’ve never seen a solar flare nearly that big,” said Eichler.

Although the motion of such a sun-grazer would be the source of the shockwaves’ energy, the actual particle acceleration would happen within the sun’s magnetic field, explains Eichler.

Traveling at a 1000 kms per second, the shockwaves would reach earth in about a day and a half. And the effects would likely be much worse than the 1859 Carrington Event, a solar superstorm that wreaked havoc on telegraph lines and caused the aurora borealis to be visible as far south as Texas.

“From the looks of the tree ring data, fortunately, such events don’t happen but once every several thousand years,” said Eichler. “But by my estimates such a comet event might be 30 times stronger than the Carrington Event.”

Such a sun-grazing event’s resulting volley of cosmic rays would be funneled in along earth’s magnetic poles where magnetic resistance is the least, Eichler explains.

When the shockwaves hit the earth’s magnetic field, it would be like the hammer of a piano hitting a string, says Eichler. It would vibrate. And when a magnetic field line vibrates, he says, it makes an electric field which excites current in wires.

“It can excite the current and burn out the circuit,” said Eichler. “That’s the danger of giant electromagnetic pulses; these huge electric fields hit tiny micro-circuitry designed to handle only small currents.”

Although not expected to be harmful to humans, such an event could be extremely devastating to our electronic grid and could quite possibly send us back into a new Stone Age, says Eichler.

As for predicting future sun-grazers?

Most sun-grazing comets are too small to even make a ripple on the solar surface.

A recent exception was Comet Lovejoy, a long period sun-grazing comet which in December 2011, was observed to unexpectedly survive its closest solar approach.

Eichler says it’s quite possible that a very large comet could graze the sun once every several thousand years.

“If the Hale-Bopp-sized comet grazed the solar corona,” said Eichler, “then you’d get a much bigger solar flare than the Carrington Event. Hale-Bopp itself may become sun-grazing in the [distant] future.”

But there is one positive. Astronomers should, in principle, get a few years notice if such a large potential sun-grazing comet comes around again.

However, with a few classified military exceptions, our electronics remain unprotected against such potential magnetospheric trauma, he says.

Today, the Carrington Event itself would be devastating, says Eichler, and it wasn’t particularly powerful or all that unusual on an astrophysical timescale.

After completing his research, Eichler says he is most surprised by the fact that we’re still here to tell the tale.

“I didn’t realize the solar system was such a dangerous place,” said Eichler. “Just the fact that we’ve gone as long as we have without worse things happening may be why we’re here.” ... rmageddon/

Published on Sep 29, 2012
A new comet has been discovered that is predicted to blaze incredibly brilliantly in the skies during late 2013. With a perihelion passage of less than two million kilometres from the Sun on 28 November 2013, current predictions are of an object that will dazzle the eye at up to magnitude —16. That's far brighter than the full Moon. If predictions hold true then C/2012 S1 will certainly be one of the greatest comets in human history, far outshining the memorable Comet Hale-Bopp of 1997 and very likely to outdo the long-awaited Comet Pan-STARRS (C/2011 L4) which is set to stun in March 2013.

The new comet, named C/2012 S1 (ISON) was found by the International Scientific Optical Network (ISON) in Russia on 21 September when astronomers Vitali Nevski and Artyom Novichonok captured it on CCD images taken through a 0.4-metre reflector. Its near-parabolic orbit suggests that it has arrived fresh from the Oort Cloud, a vast zone of icy objects orbiting the Sun, pristine remnants of the formation of the Solar System.

C/2012 S1 currently resides in the northwestern corner of Cancer. At magnitude +18 it is too dim to be seen visually but it will be within the reach of experienced amateur astronomers with CCD equipment in the coming months as it brightens. It is expected to reach binocular visibility by late summer 2013 and a naked eye object in early November of that year. Northern hemisphere observers are highly favoured. Following its peak brightness in late November it will remain visible without optical aid until mid-January 2014.

Comet brightness predictions sometimes exceed their performance. Amateur astronomers of a certain age may remember the Comet Kohoutek hype of 1973 -- not quite the 'damp squib' it has been portrayed, since it reached naked eye visibility! Even if C/2012 S1 takes on the same light curve as Kohoutek it is certain to be spectacular, quite possibly a once-in-a-civilisation's-lifetime event.

A comet compared to the sun is like a speck of dust compared to the mass of the earth. No comet is large enough that it can affect the sun in any way whatsoever. The solar flares and sunspots are many times larger that the planet earth. A 30 km comet is miniscule in comparison. The sun won't even notice it.

Comets have been grazing and hitting the sun since the beginnings of the solar system, why are those two special? It's like stopping a train with a near-miss snowball.

I'm actually surprised that an astrophysicist would be amazed the solar system is a dangerous place. Tell the fool to look at the moon or Mars someday to see just how dangerous it can be. :lol:

There were already 9 Brilliant Comets Ever Seen but C/2012 will be the largest ever greater then the comet of 1680 with a 18.8 magnitude
The newly-discovered Comet C/2012 S1, or Comet ISON will be swinging through the inner solar system over the next year and a half and astronomers believe that as it gets closer to the Sun it may be brighter than the moon and visible during the day.

It is called ISON because it's named after the International Scientific Optical Network in Russia.

Spotted beyond the orbit of Jupiter September 24, astronomers have noted some interesting facts about Comet ISON.

The comet is larger than most, which gives it the potential to be quite spectacular come next November. Some projections have shown that Comet ISON could reach between -10 to -16 magnitude brightness, which has the potential to outshine the full moon (magnitude -13). Its size also gives it the potential to generate very long tails.

Its orbit will take it very close to the Sun. It should be just 1.8 million kilometres away from the Sun as of November 28 next year, as it swings under the Sun's south pole. If its as bright as predicted, and it maintains its integrity as it approaches, it may end up being visible during the day.

ISON's orbit is very close to that of The Great Comet of 1680 (C/1680 V1), and ISON will pass by Earth at a distance of 60 million kilometres, just a bit closer than C/1680 V1 (63 million kms). C/1680 V1 is about 4 billion kms away from the Sun right now, so Comet ISON is definitely not the same comet. However, the two comets may very well have been parts of the same larger object at some time in the distant past, which would account for their similar orbits.

On September 30 next year, Comet ISON's orbital path looks to be lined up straight over Mars' north pole. However, it will miss that direct pass over the red planet by just a matter of a few days, because it doesn't cross over Mars' orbit until October 3. Still, the Curiosity and Opportunity rovers should get a spectacular view of the comet as it passes.

Comet ISON's orbit is angled to the north of the ecliptic, or 'invariable plane' of the solar system. If you were to view the solar system from the outside, you would see that all the planets orbit in the same plane (or very close to it). The only time Comet ISON is south of this plane of the solar system is from just before it crosses Venus' orbit, until it swings around the sun.

When Comet ISON first crosses Earth's orbit, on November 1 or 2 next year, it will be 'ahead' of Earth, but after it swings around the Sun and starts to head out again, its path will take it almost directly over the Earth on December 30 or 31, hopefully giving us a rather impressive New Years 2014 display.

Right now, Comet ISON should be visible to anyone with a large enough telescope, and can be seen at about 6.5 degrees east of the star Pollux, in the constellation Gemini. It should be visible to smaller telescopes, or perhaps binoculars closer to the end of next summer, but it won't be until late October or early November next year, when it is between the orbits of Mars and Earth, that the real show should begin.

When a comet is still out beyond the orbit of Jupiter, it is already generating what's known as the 'coma' — an atmosphere of gas generated by the comet ice being melted by the Sun. As it travels between the orbits of Mars and Earth, the heating from the Sun becomes more intense and the comet's two tails begins to form, trailing off behind it - one made of ionized gases that always points direction away from the Sun and another made of dust that is blown off away from the sun, but that curves back along the path the comet is tracing through space. By the time it reaches and passes Earth's orbit, its tails are typically quite well-formed and can be long and bright. With Comet ISON's size, it is possible that its tails could stretch all the way back to Mars.

Unfortunately, this is all just educated guesses, though. From where Comet ISON is now, there's no way to tell for sure what it is going to look like when it gets closer to the Sun. Comets have been known to just fizzle out, regardless of their potential. For example, on August 30, 2011, Comet Elenin — seen as a doomsday comet by some — simply broke up into smaller pieces and disintegrated. So no one wants to say anything too definite or hopeful about Comet ISON just yet. It will all depend on the comet's composition.

I now feel a certain obligation to mention that there's no chance of Comet ISON hitting the Earth.

Not only does Comet ISON first cross Earth's orbit a full 75 days before Earth reaches that point in its orbit, but even if they were timed perfectly to arrive at that point at the same time, with the angle of Comet ISON's orbit, it would just pass harmlessly over the north pole. Also, the second time it crosses Earth's orbit it will also be above the planet, missing us by nearly 65 million kilometres.

So, don't worry if you hear new doomsday prophecies about Comet ISON (maybe the Mayans were off by a year?) and just keep an eye on the skies to see if this new comet can reach its full potential. Oh, and one other thing, with this comet swinging so close to Earth's orbit on its approach to the Sun, it's possible we may see a nice meteor shower in the middle of January 2014, due to the particles left behind from the comet's dust tail.

If you would like to see the orbit of Comet ISON, NASA has a neat java applet that plots it for you, lets you zoom in and out of the view and watch as the planets and comet orbit the sun. Just follow this link. ... 39189.html

They have said such things about other comets and then had their degree of magnitude downgraded when it appeared. Guess we'll just have to wait and see...

LOL - there's probably an Armageddon "Wheel of Fortune" that they go to when the previous one doesn't pan out.

Yeah well, the Mayan "End of the World" prediction/theory/lottery was a bust so, someone has to come up with another theory LOL.
I like the "Armageddon Wheel of Fortune" theory, it is the most plausible for the tin hat crowd.
