It seems that scientists have finally discovered the energy source of the colorful Aurora Borealis or Northern Lights. They found that the energy comes from a stream of charged particles from the sun flowing like a current through twisted bundles of magnetic fields connecting Earth's upper atmosphere to the sun.

 

The energy is then abruptly released in the form of a shimmering display of lights visible in the upper latitudes of the Northern Hemisphere. In March, satellites detected a burst of northern lights, or auroras borealis, over Alaska and Canada. During the two-hour light show, the satellites measured particle flow and magnetic fields from space.

 

To scientists' surprise, the geomagnetic storm powering the auroras raced 400 miles in a minute across the sky. The storms estimated power was equal to the energy released by a magnitude 5.5 earthquake.

 

Simply fascinating and beautiful, I can sometimes see the lights here if I look to the north. If you have never seen them it is really something to behold. It is almost hypnotic the way the lights move and fade in and out of various colors.

 

Update, further information was released today. Read Here.

I've always wanted to see these wonders in person. Maby someday.... :D

 

The 5.5 magnitude thing was interesting also... I always thought it was beacuse of reflections of some sort. :P

I too thought that had been known for awhile....

 

They truly are beautiful, I've only seen them a handful of times.

Dinna realize this was an old entry 'till I'd already decided to post. 'Twas Seranikai's presence that tipped me off. May he fly and win, wherever he be.

 

I, too, have been under the assumption that scientists had explained the aurora decades ago. Of course, thanks to you, CzaR, I now know better. It's amazing how many mysteries are still open for science....

 

Naturally, much of the stuff that ever hits the mainstream is either old hat, flawed to the point of absurdity, or inflated speculation. Good science, like good wine, is hard to come by. I guess. What do I know? Never mind.

 

But yeah, the aurora borealis? Amazingest show on Earth. I've only seen some very faint, greenish ones here in Finland. Haven't ever actively sought out the best seats, though, so can't complain.
