Solar Orbiter captured the most detailed view of a solar flare, observing the build-up of events that lead to the explosion.

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

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 ...

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

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 ...

At the end of 2024, ESA's Solar Orbiter was lucky to witness a strong solar flare - and observed the events leading up to this firework with ...

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 ...

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

The ESIS-II mission aims to capture high-speed “snapshot” images of the Sun’s transition region and corona. To achieve this, ...

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 ...
