ESA’s Solar Orbiter discovered cascading magnetic avalanches on the Sun, triggering powerful solar flares and particle storms ...

The sun’s rhythmic rise and fall in the sky can make it easy to forget that our star is unpredictable—a roiling, burbling mass of magnetically knotted plasma that governs the entire solar system. The ...

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

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 ...

An object from outside the Solar System has been spotted hurtling towards the Sun, which if confirmed would be the third visitor from the stars ever detected, the European Space Agency said Wednesday.

For nearly five years, a Sun-observing probe has been making close approaches to the Sun, capturing close-up views of the star’s polar regions to collect clues about its magnetic activity, corona, and ...

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