In a dramatic escalation of solar activity, the sun has unleashed an X8.3 flare — 2026’s strongest yet — causing radio ...

A rapidly growing sunspot has fired off at least 18 M-class and three X-class flares in just 24 hours, including an intense ...

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

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 ...

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

"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 ...

STUNNING Northern Lights could fill the night sky over the UK tonight after a powerful mass was splurted from the sun. A coronal mass ejection (CME) was ejected from the sun and is expected to ...

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 ...

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