Solar physicists have long known that the sun stores staggering amounts of magnetic energy, but the exact trigger that lets that energy explode in a solar flare has been stubbornly elusive. Now, a new ...

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 ...

A strong solar flare peaked just after 9 a.m. Tuesday, but what does that mean? Can it be seen from Earth?Tuesday's solar flare was not the first this year or even this month. Here is more information ...

Considered our solar system's largest explosive events, solar flares can sometimes be as strong as a billion hydrogen bombs. Those with enough energy output to rank as an X-class have the potential to ...

The Sun looks like a warm yellow sphere with a surface covered with glowing messy hair. The yellow glow extends to the edges of the image, with some regions brighter than others. Many bright yellow ...
