Aurora borealis

A recent study suggests the aurora-like STEVE and "picket fence" phenomena are generated by low-altitude electric fields parallel to Earth's magnetic field.

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 huge solar filament eruption has hurled a coronal mass ejection (CME) toward Earth. The CME is expected to hit Earth on Sept. 19 and may trigger extensive auroras.

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.

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

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.
