A Giant Breach in Earth's Magnetic Field
NASA Dec. 16, 2008: NASA's five THEMIS spacecraft have discovered a breach in Earth's magnetic field ten times larger than anything previously thought to exist. Solar wind can flow in through the opening to "load up" the magnetosphere for powerful geomagnetic storms. But the breach itself is not the biggest surprise. Researchers are even more amazed at the strange and unexpected way it forms, overturning long-held ideas of space physics.
"At first I didn't believe it," says THEMIS project scientist David Sibeck of the Goddard Space Flight Center. "This finding fundamentally alters our understanding of the solar wind-magnetosphere interaction."The magnetosphere is a bubble of magnetism that surrounds Earth and protects us from solar wind. Exploring the bubble is a key goal of the THEMIS mission, launched in February 2007. The big discovery came on June 3, 2007, when the five probes serendipitously flew through the breach just as it was opening. Onboard sensors recorded a torrent of solar wind particles streaming into the magnetosphere, signaling an event of unexpected size and importance.
"The opening was huge—four times wider than Earth itself," says Wenhui Li, a space physicist at the University of New Hampshire who has been analyzing the data. Li's colleague Jimmy Raeder, also of New Hampshire, says "1027 particles per second were flowing into the magnetosphere—that's a 1 followed by 27 zeros. This kind of influx is an order of magnitude greater than what we thought was possible."
So what does this actually mean?
The magnetosphere helps to shield the ionosphere from the solar wind. So without this shield, we then get blasted from the sun whenever there is a big solar flare. Without protection from solar flares our electronics would get fried. (and you think the lack of posts recently on theLucky is bad now)
But don't go into a panic yet, the magnetosphere is not our only protection from solar wind, our dense atmosphere helps out as well.
I guess someone could make a case that this might contribute in making our poles shift, (north pole now becomes south) but I am not so sure of this. Because we are overdue for this shift to happen. And I am sure on the internet somewhere you can find information on when the pole do shift it will be the demise of man kind. But I think this will have no effect on the poles.
So what I do find interesting is the timing. So we have a hole in our magnetoshpere 4 times the size of earth over the North Pole. And this happens a few weeks after we detonate 9 atomic bombs in the Atlantic Ocean at the Magnetic North Pole.
War is crime---On November 17 and 18, 2008 nine H-Bombs were exploded below the Arctic Ocean, near the North Magnetic Pole, within Canadian waters. The explosions were concentrated in an area about 16 km by 16 km (10 miles by 10 miles), were in the 5 to 10 Megaton range, all were 10 km (6.2 miles) deep. They punched a hole in the crust and will allow petroleum
At a later point I will get into why we blew a gigantic hole in the North Pole. But how come I am the only person that thinks a giant hole in the sky that can possible kill all electronics on the earth is a big deal? People flipped out during Y2K when they thought that their VCR clock was not going to be able to record Law and Order at 9PM on Monday nights.
I just don't know anymore.
But the good news about this is the hole is directly over the North Pole, and hopefully it might cancel Christmas.
