An aurora borealis (northern lights) rises above Alaska's Denali National Park in 2006. For an April 2009 study, THEMIS satellites (inset) helped reveal how fast-swirling, curving "space tornadoes" wider than Earth itself help "ignite" auroras.


Word is that they sound like a freight train and occur mainly over intergalactic trailer parks.
If we could only harness that energy, solution to our problems...
Tornadoes huh? Caused by global warming, it’s all Bush’ fault!
i saw them here(76.8N) over the lake once in the late 70's and again in the early 80's, mostly green with some red. very beautiful and quite hypnotic...
thanks LucyT.
UNEXPECTED SOLAR ACTIVITY: The sun produced an unexpected burst of activity on April 23rd when an enormous prominence rose over the northeastern limb and erupted. A coronal mass ejection (CME) billowed away from the blast site, but the billion-ton cloud is not heading toward Earth. Visit http://spaceweather.com for movies of the event.
