Solar physicists have long known that the sun stores staggering amounts of magnetic energy, but the exact trigger that lets ...

Just as avalanches on snowy mountains start with the movement of a small quantity of snow, the ESA-led Solar Orbiter spacecraft has discovered that a solar flare is triggered by initially weak ...

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

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 ...
