The Sun released a strong solar flare on Tuesday, Feb. 3, following several eruptions in the preceding days, raising the possibility of increased geomagnetic storm activity. Nasa’s Solar Dynamic ...

Solar Orbiter captured the most detailed view of a solar flare, observing the build-up of events that lead to the explosion. Reading time 3 minutes On September 30, 2024, the Sun unleashed a powerful ...

For the first time, scientists believe they have captured direct evidence of the mechanisms that trigger a solar flare. These massive explosions, generated by the Sun, release staggering amounts of ...

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 ...

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 ...
