The aurora borealis that took place on St. Patrick's day was spectacular, but it was also the first time that thousands of citizen scientists tweeted about the aurora to help NASA construct a detailed global map of the event.
On January 22, a January 22 M8.7 class flare caused the biggest solar storm since 2005. Airplanes had to change routes, and the power grid and satellites were affected. It also caused some of the best auroras ever seen.
If you go to Skógafoss — a waterfall in the south of Iceland — when the full moon is shining bright during the aurora season, perhaps you'll catch this magical scene. And meet an elvish princess who looks like Björk.
The auroral lights dancing across the night sky is a beautiful sight. Viewed from the ISS they look even better, but when you combine that with a couple of Russian spaceships, it truly is out-of-this-world. [NASA via MSNBC]
