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.

'Alien' lights in Norway were a NASA mission, not an extraterrestrial visit.

A gargantuan green dragon hisses in the sky over Iceland this month and its appearance has scientists stumped.

Where should you go to get the best look at the dancing, dazzling display known as the aurora borealis?

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.

There is a beautiful mystery in the sky, and its name is Steve.

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.

In a new special episode on Science Channel, explore Jupiter with the Juno spacecraft.

New research shows the closest-ever views of features in Jupiter's swirling auroras, revealing the complicated footprints left by its moons Io and Ganymede.

The Earth recently put on a spectacular show for astronauts aboard the International Space Station.

Deep in the sun's core, buried under hundreds of thousands of miles of twisting and convecting hydrogen and helium, a nuclear fire rages.
