Aurora Borealis

Magnetic storms can create amazing auroras, but they also have the capacity to impact our power grid.

Experts are concerned that these blood-red light shows could be causing unknown problems for astronomy and communication.

A strong solar storm triggered magnificent aurora displays over the weekend. Here we take a look at some of the best northern lights and southern lights photographs from around the world.

A striking new image shows bright orange auroras dancing in the night sky above Canada. But auroras should never be this color, so what's going on?

Want to see the northern lights (aurora borealis) or the southern lights (aurora australis)? Good news — The next four to five years will provide optimal conditions for some dazzling displays.

A powerful solar storm triggered stunning aurora displays around the world. Here we take a look at some of the best photographs of the recent northern lights outburst.

The sun has launched a surprise coronal mass ejection directly at Mars, which could spark auroras on the Red Planet and potentially erode part of Mars' remaining atmosphere when it hits on Sept. 1.

The northern lights have been seen high in the Arctic Circle, indicating the start of the aurora season, which will become more apparent as we approach solar maximum.

The way in which the radiant displays of colors in the sky known as auroras form on Earth may be how these lights arise throughout the solar system, according to new findings from Mercury.

Scientists have observed an aurora glimmering in infrared light, created by the interaction of energetic cosmic particles and carbon dioxide in Earth's atmosphere.

It's believed that only 3% of all sunspots display reverse polarity as this one does.

Dazzling aurora displays — triggered by a severe solar storm — have been seen around the world. We take a look at some of the best photos here.

A mystifying swirl of light recently appeared in the night sky above Alaska, briefly outshining a vibrant auroral display.

The STEVE phenomenon was spotted across the U.S. and in parts of the U.K. after the most powerful solar storm to hit Earth for six years smashed into our planet.

A surprise solar storm supercharged auroras across the U.S. and Europe last night (March 23), with sightings of the colorful displays reported from as far south as New Mexico and Arizona.

A 'hole' in the sun's upper atmosphere may soon generate another geomagnetic storm here on Earth, creating auroras in places farther from the poles than usual.
