NASA’s Solar Dynamics Observatory captured an X2.8-class solar flare and a pair of m-flares that preceded it in multiple ...

Deep in the frozen heart of Antarctica, the South Pole Telescope has been watching one of the most extreme neighborhoods in our galaxy, and it's just caught something extraordinary happening there.

Scientists watched a solar flare grow from tiny magnetic sparks into a violent plasma-raining avalanche on the Sun.

Solar Orbiter observations show that a medium-class solar flare formed through cascading magnetic reconnection events, ...

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 ...

ESA's Proba-3 mission, made up of twin spacecraft capable of aligning to create artificial eclipses, has captured "rare" ...

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 ...

Solar Orbiter saw that, in the lead-up to a solar flare, twisted magnetic fields break and reconnect, creating an outflow of energy that subsequently rains down through the Sun’s atmosphere in ...

NASA explained that the flare was classified as an X1.9 flare. X-class flares are the most powerful type of solar flares. The number 1.9 shows how strong the flare was within this highest category.

The northern lights may not have been as bright as you expected, but Earth’s atmosphere was still highly active.
