Aurora Borealis

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.

Aurora hunters claim that, to look to the night sky in search of these beautiful displays, the dates around the equinoxes are the best.

The powerful solar storm that struck Earth earlier this week treated an American astrophotographer to unexpected aurora displays during a shooting trip to California's Death Valley.

Before capturing "unreal" footage of auroras from the International Space Station, Josh Cassada was troubleshooting how to fit a fifth person into a four-seat SpaceX spacecraft.

A series of powerful solar storms set the sky ablaze in the last two days of February, with aurora sightings reported unexpectedly far away from their usual territories.

NASA astronaut Josh Cassada captured a stunning shot of green auroras dancing in Earth's skies from his vantage point on the International Space Station.

A solar storm that swept across Earth on Monday (Feb. 27) forced SpaceX to delay a Starlink launch and temporarily disrupted operations of several Canadian oil rigs.

Powerful solar wind is blowing from the sun these days, setting the sky ablaze with auroras as far south as England's capital London. And more is yet to come.
