Once again scientific assumptions are turned on their head:

"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 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.

The size of the breach took researchers by surprise. "We've seen things like this before," says Raeder, "but never on such a large scale. The entire day-side of the magnetosphere was open to the solar wind."

"When I tell my colleagues, most react with skepticism, as if I'm trying to convince them that the sun rises in the west."

...you can imagine our surprise when a northern IMF came along and shields went down instead," says Sibeck. "This completely overturns our understanding of things."
