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.

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.
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.
Deep in the sun's core, buried under hundreds of thousands of miles of twisting and convecting hydrogen and helium, a nuclear fire rages.
The aurora borealis, also known as the northern lights, is the rippling night-sky light display found at the northernmost reaches of the Earth.
Researchers may have finally found the ghostly footprint of Jupiter's moon Callisto in the planet's auroras.
The shimmering dance of the aurora shines in a video released recently by the European Space Agency.
