Researchers may have finally found the ghostly footprint of Jupiter's moon Callisto in the planet's auroras.
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.
The shimmering dance of the aurora shines in a video released recently by the European Space Agency.
A guide who helps tourists see auroras in Sweden recently captured jaw-dropping views of the northern lights himself, showing the ethereal lights dancing above a snowy landscape.
A group of citizen scientists helped to discover a new type of aurora named "Steve," and now NASA wants your help photographing the unusual phenomenon.
New work helps to codify the cause and properties of "Steve," an aurora-like phenomenon documented by citizen scientists as it streaked across the sky in western Canada.
A minor solar storm will reach Earth Wednesday (March 14) and could supercharge the planet's auroras, making them visible from the northernmost parts of the U.S., space weather officials say.
Thanks to a solar storm, the northern part of North America may see a dazzling auroral display tonight.
The origins of "pulsating auroras" — intense flickering displays of light high up in Earth's atmosphere — are now revealed after a decades-long hunt, a new study finds.
An explosion of colors lights up the evening sky as a rare double "moonbow" meets the northern lights in this stunning, star-speckled view.
European Space Agency astronaut Paolo Nespoli captured stunning imagery of Earth in his final days aboard the International Space Station.
Auroras may be visible across Canada and the northern parts of Montana, North Dakota and Michigan Nov. 8 to 11, courtesy of a hole in the sun's corona.
Astronomers have finally detected X-rays blazing from Jupiter's mysterious southern lights, a new study finds.
A massive, glowing bubble of light erupted in the sky above northeastern Siberia, which may have been created by a test missile launch.
A strong solar storm recently sparked a whole-planet aurora on Mars more than 25 times brighter than any seen before on the Red Planet, researchers say.
Active Region 2673 blasted out yet another solar flare early this morning (Sept. 8), its sixth intense burst of high-energy radiation since Monday (Sept. 4).
What's powering the powerful auroras at Jupiter's poles? New results suggest it's not the same mechanism powering the most energetic auroras on Earth, contrary to scientists' expectations.
