Aurora borealis

Italian astronaut Samantha Cristoforetti reveals breathtaking new auroral images from the International Space Station.

Auroras shone in many polar regions last night following a moderate-sized solar storm. And more might be coming after a more recent sun eruption.

A moderate-sized aurora glowed eerily green within view of the International Space Station crew, following a burst of activity from the sun.

The sun has spat out two clouds of plasma in the past two days, which might trigger beautiful aurora displays observable as far south as New York later this week.

A surprise solar storm bashed Earth on Aug. 7 and 8, triggering an appearance of the mysterious glowing phenomenon called STEVE.

Earth was zapped by a solar storm on Sunday (Aug. 7) and the activity generated enormous auroras, or northern lights, across a swath of the planet.

A geomagnetic event around 41,000 years ago sent the aurora wandering for centuries, as far south as the equator.

New footage shows the mysterious auroral phenomenon called STEVE emerging from a blood-red arc of light in New Zealand in 2015.

A group of 13 telescopes allowed researchers to observe the process behind a unique type of aurora, known as auroral beads, for the first time.

NASA's Solar Dynamics Observatory captured yet another solar flare blasting from the same overactive sunspot that triggered radio blackouts and stunning aurora displays on Earth earlier this week.
