Voitte valmistautua vuoteen 2012 sillä asenteella, että tulee vielä aika monta muuta asiaa joihin NASA yms. vastaa "This finding fundamentally alters our understanding".
From NASA News (h/t to Geoff Sharp)
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 years ahead could be especially lively. Raeder explains: “We’re entering Solar Cycle 24. For reasons not fully understood, CMEs in even-numbered solar cycles (like 24) tend to hit Earth with a leading edge that is magnetized north. Such a CME should open a breach and load the magnetosphere with plasma just before the storm gets underway. It’s the perfect sequence for a really big event.”
Sibeck agrees. “This could result in stronger geomagnetic storms than we have seen in many years.”
