(NEXSTAR) – A solar radiation storm stronger than one we’ve seen in over two decades is in progress, the Space Weather ...

Federal forecasters are warning that a powerful X-class solar flare could trigger strong radio blackouts and strain power ...

F or all of its life-sustaining energy, the sun is pretty chaotic. Roiling plasma covers its surface along with fluidic snarls of magnetic fields that birth solar flares. These fiery outbursts occur ...

"This is one of the most exciting results from Solar Orbiter so far." ...

Scientists watched a solar flare grow from tiny magnetic sparks into a violent plasma-raining avalanche on the Sun.

The ESA's Solar Orbiter has discovered that solar flares act like avalanches, growing from weak disturbances into powerful ...

Just as avalanches on snowy mountains start with the movement of a small quantity of snow, the ESA-led Solar Orbiter ...

Solar Orbiter has captured the clearest evidence yet that a solar flare grows through a cascading “magnetic avalanche.” Small, weak magnetic disturbances rapidly multiplied, triggering stronger and ...

A powerful X-class solar flare has unleashed a severe geomagnetic storm, arriving faster and stronger than predicted. Join ...

STUNNING Northern Lights could fill the night sky over the UK tonight after a powerful mass was splurted from the sun. A ...

Colorful auroras could dazzle skywatchers again on Monday night amid a severe geomagnetic storm and what the National Oceanic ...

Solar physicists say they have found a key source of intense gamma rays unleashed when Earth's nearest star produces its most violent eruptions. In findings published in Nature Astronomy, scientists ...
