Big Pic: Aurora Light Up Antarctic Night: If the aurora glows over Antarctic and there’s no one to see it, does it have any color?
Beautiful, fine detail in the auroral structure. Must’ve been quite a show!
A great pic of northern lights from Tumblr Campbench who writes:
ONE of the photos I snapped this evening. It started around 9:30pm (central time) but died soon after. It started up again around midnight and set the sky on fire. I have never before seen the lights this bright and this moving! “Waves” of what I can assume were electro-magnetic in origin would pulsate across the sky. It was definitely one of the most awesome experiences with nature I have ever had (and well worth the frostbite)!
Taken on Lake Superior, Duluth, MN.
I will post more photos to my blog when I get the chance.
(Update: also, check out the Campbench Tumblr. There are more great pics there and more to come later!)
A longstanding mystery about the origin of the energetic particles that cause Earth’s dramatic aurora displays may have been solved.
The electrons responsible for the auroras — also known as the northern and southern lights — are likely accelerated to incredible speeds in an active region of Earth’s magnetosphere, according to a new study. This region is 1,000 times larger than scientists had thought possible, providing enough volume to generate lots of the fast-moving electrons.
