We observed a powerful flare and a huge burst of radio waves from our nearest stellar neighbour, Proxima Centauri, indicating violent space weather around the star.

The sun’s phenomena, like flares, can cause solar particles to enter the Earth’s atmosphere, with material effects.

When dozens of US mines planted in waters off the Vietnam coast detonated almost simultaneously in 1972, all eyes turned to the Sun for an explanation.

At a time in the sun's cycle when space weather experts expect less solar activity, our star is going bonkers with solar flares and coronal mass ejections. What effects will Earth feel?

Our growing dependency on satellites for all forms of communication has made the problem of space weather even more acute.

Geomagnetic storms can interact with particles near Earth, causing issues for satellites and other tech. Researchers send balloons 20 miles into the sky to figure out just what's going on up there.
When the sun flares, space weather is on its way to Earth.

Our power grid infrastructure on Earth is more vulnerable to space weather than previously thought – with susceptibility in more regions and even during quiet geomagnetic periods.
