How are the northern lights colors created? MINNEAPOLIS— From Seattle in the Northwest, to across the world in Spain, and right back in Minnesota, the human collective looked north for a few nights asa massive light show performed for one of its largest audiences ever. "This isthe strongest...
Physicists led by the University of Iowa report definitive evidence that auroras that light up the sky in the high latitudes are caused by electrons accelerated by a powerful electromagnetic force called Alfven waves.

It was this solar storm that created the widely seen auroras, and many amateur astronomers and even regular people without any particular astronomical knowledge were able to capture beautiful images because of developing camera technology. “Cameras — even standard cell phone cameras — are much more...
Low light, cold temperatures and the unpredictable nature of auroras make them a rather tricky subject. That's why we have created a "Where and how to photograph the aurora" guide that includes the best techniques and camera settings to help you get started. Speaking from experience, it is ...

When this radiation and these particles reach the Earth's magnetic field, they interact with it at the poles to produce the auroras (borealis and australis). Solar flares can also disrupt communications, satellites, navigation systems and even power grids. The radiation and particles ionize the at...

You will even start to see some Nebulae, Galaxies, Globular Clusters, the Milky Way, Meteorites, Auroras, and more. If you own a point-and-shoot (compact) camera or are just using your smartphone, you will need to use the manual settings to shoot long-exposure images. Smartphones like ...
Auroras: Auroras are electrified particles trapped by the magnetosphere and directed toward the poles. Near the poles, the lines of the magnetic fields converge, causing the charged particles to interact and form beautiful bands of colorful light in the sky. ...
“Our tractors acted like they were demon possessed,” Elaine Ramstad, an aurora chaser who’s family works a farm in northern Minnesota, told Spaceweather.com.“All my cousins called me during the May 10 storm to tell me that ‘my auroras’ were driving them crazy while they were planting...
