The strongest solar flare in nearly two months erupted from the sun Tuesday, causing a minor geomagnetic storm as charged particles from the sun passed by the planet. Subscribe to read this story ...

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 ...

Explosive sunspot AR3663 and its bigger cousin AR3664 are the current main solar flare players, unleashing flare after flare. We're struggling to keep up! When you purchase through links on our site, ...

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 ...

The Sun’s surface dances. Giant loops of magnetized solar material burst up, twist, and fall back down. Some erupt, shooting radiation flares and particles out into space. Forced to observe this dance ...

Magnetic avalanches are chain reactions of tiny energy bursts on Sun. They start small but rapidly amplify into massive solar flares. Each cascade releases intense heat, light, and high-speed ...
