A scarlet fan spread across the skies over Japan 1,400 years ago, and it's been puzzling astronomers ever since.
The aurora borealis, also known as the northern lights, is the rippling night-sky light display found at the northernmost reaches of the Earth. The south has a corresponding aurora australis, also known as the southern lights. The northern and southern auroras occur when charged particles released by the sun, called the solar wind, are guided along the Earth's magnetic field to its poles and interact with particles in the upper atmosphere there. How to see the Northern Lights.
Where should you go to get the best look at the dancing, dazzling display known as the aurora borealis?
The pattern of light was unfamiliar and strangely perfect, reaching out toward the horizon like a set of celestial sand dunes.
Dark fluffy thunderclouds don't just fuel dramatic storms, they also produce some of the most energetic flashes of light on the planet.
Six decades ago, a magnificent red splotch spread across the sky — and now, scientists think that by piecing together footage of the event, they better understand even older auroras.
Scientists finally have an explanation for the weird celestial phenomenon called STEVE, which looks and behaves a lot like an aurora but has key differences.
A high-altitude version of the northern lights can create a headwind for some orbiting satellites, new research confirms.
A gargantuan green dragon hisses in the sky over Iceland this month and its appearance has scientists stumped.
The northern lights just got a boost thanks to a big hole in the sun's atmosphere, and there could be something of a repeat showing tonight (Sept. 11).
New images from the Hubble Space Telescope show Saturn's ultraviolet auroras swirling at the planet's north pole in the months before and after the northern summer solstice.
Active space-based experiments can deliver crucial insight into the space environment that has become increasingly vital to national security and the global economy.
Most of us are lucky to catch a glimpse of a stunning aurora painting the skies once or twice in our lives — but astronauts have better odds of spotting the beautiful phenomenon.
A new type of aurora has been spotted on Mars, and thieving streams of solar wind may be to blame, a new study shows.
Researchers for the first time recorded the gas giant's vibrating plasma signal to Enceladus. And now you can listen to it too.
