Solar flares have an enormous impact on the wider Solar System. These sudden releases of energy can cause geomagnetic storms on Earth and radio blackouts too, like the one that's happened in the last ...

Observing the aurora is one of the few hobbies where “going outside and staring into the dark” qualifies as sound planning.

Earth just experienced a rare S4 solar radiation storm, the most intense since 2003 — powerful for satellites and astronauts, ...

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

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 ...

The planet is experiencing the most powerful solar event since 2003—and it's bringing spectacular Northern Lights.

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 ...

ESA’s Solar Orbiter discovered cascading magnetic avalanches on the Sun, triggering powerful solar flares and particle storms, revealing hidden processes that could protect satellites and advance ...

Scientists tracked active solar region NOAA 13664 for 94 days, showing how persistent magnetic complexity drives flares and space weather.

Our Sun’s outer atmosphere, the corona, is millions of degrees hotter than it should be, and no one knows why.
