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."

A Giant Breach in Earth's Magnetic Field

Magnetic Portals Connect Sun and Earth
During the time it takes you to read this article, something will happen high overhead that until recently many scientists didn't believe in. A magnetic portal will open, linking Earth to the sun 93 million miles away. Tons of high-energy particles may flow through the opening before it closes again, around the time you reach the end of the page.
"It's called a flux transfer event or 'FTE,'" says space physicist David Sibeck of the Goddard Space Flight Center. "Ten years ago I was pretty sure they didn't exist, but now the evidence is incontrovertible."

I'LL BE JUST FINE, SAYS PLANET

I'LL BE JUST FINE, SAYS PLANET
THE planet Earth has dismissed claims it is in danger from global warming, stressing the worst that could happen is the extinction of the human race.
'If you don't mind, I've got some orbiting to do'The Earth spoke out after a series of books, television programmes and environmental campaigns urged people to do everything in their power to 'Save the Planet'
Earth, aged 4,000,000,000, said last night: "I'll be absolutely fine, seriously. I might get a bit warmer and a bit wetter, but to be honest, that actually sounds quite nice."Try living through an ice age. Pardon my French, but it's absolutely fucking freezing."
The planet, based 93 million miles from the Sun, said it was 'sick and tired' of being drawn into arguments about human behaviour.
"Look, I'm just a planet doing its thing, alright? If you want to live on me, that's your business, but I've got important planet stuff to do, okay?
"Try being in elliptical orbit for five minutes, or balancing your gravitational pull with a medium-sized moon. Let me assure you, it's no fucking picnic."
The planet said environmental campaigners should change their slogan from 'Save the Planet' to something more relevant such as 'Save Your Sorry Arse'.
Earth added: "Okay, so there may come a time when, for a variety of reasons, I am no longer able to support pandas, polar bears, and humans, but you know what? Life goes on.
"Who knows, I might end up being a haven for toads."

Climate Scientists: Use Spaceships To Block Out The Sun
Global warming alarmists, who have routinely dismissed evidence that the Sun is the main driver of climate change, are now calling to block out the celestial body that supports all life on Earth in a set of bizarre new proposals to “geo-engineer” the planet.
One idea being promoted is a madcap plan to send a fleet of shiny spaceships to form a physical cloud between the Sun and the Earth, covering half the diameter of the entire planet.
“Political inaction on global warming has become so dire that nations must now consider extreme technical solutions - such as blocking out the sun - to address catastrophic temperature rises, scientists from around the world warn today,” reports the Guardian
The fact that sunspot activity and solar radiation have driven natural climate change throughout history is routinely dismissed by man-made global warming advocates who insist that human produced CO2 is to blame for global temperature increases, despite the fact that no global warming has been observed for the past 10 years and strong evidence suggests the planet is now embarking on a significant cooling trend. In addition, it was recently revealed that Arctic ice has actually grown by around 30 per cent in the year since August 2007.
