A reservoir of aurora-inducing electrons trapped in the magnetosphere could be 1,000 times larger than previously thought.

Overnight on October 4-5, 2012, a mass of energetic particles from the atmosphere of the Sun were flung out into space, a phenomenon known as a coronal mass ejection. Three days later, the storm from the Sun stirred up the magnetic field around Earth and produced gorgeous displays of northern lights. NASA satellites track such storms from their origin to their crossing of interplanetary space to their arrival in the atmosphere of Earth.
Photographer Chad Blakley and video editor Tom Malkowicz have outdone themselves in a compilation of Northern Lights from 2012 and 2013. Some of the sequences were reproduced to deliver a near 'just like you were there' real-time feel.
Photographs capture the full colors in aurora displays, unlike the human eye.
Celebrate the arrival of winter solstice with some spectacular photographs capturing the interactions between our sun and the planet we call home.
The northern lights dance in a breathtaking display over Sweden.

When a small NASA-funded rocket launched off planet Earth this month in a dazzling liftoff, it wasn't headed for the final frontier. Instead, the rocket had a closer target: the northern lights dancing over Alaska.
Astrophotographer Brian Drourr took this image on June 8, 2014 from Champlain Valley, Vermont. See how he captured the aurora view here.
Stunning images of the night sky from around the world show everything from swirling green auroras and star trails to the bulging Milky Way galaxy and the Big Dipper constellation.
The night sky never looked so inviting. From light rays framing the Big Dipper above the Alps to the eerily stunning aurora hovering atop Norway, the winners of a dark skies photo contest delight with their upward gazes.
