When the surface of the Sun exploded with activity in May 2024, Earth was hit by the biggest solar storm in more than two ...

Scientists develop a forecasting system that predicts high-risk windows and regions for solar superflares, using 50 years of X-ray data and machine learning techniques.

Add Yahoo as a preferred source to see more of our stories on Google. Over the past 24 hours, the sun has been especially active, unleashing a rapid-fire series of powerful solar flares, including an ...

As if returning to the Moon’s vicinity hadn’t already had enough things to delay it, now risky space weather could get in the ...

The massive sunspot that sparked an "extreme" geomagnetic storm in May 2024 unleashed hundreds of other dangerous solar flares, including a hidden X-class outburst, a new paper reveals. The study sets ...

Three powerful outbursts of solar plasma are barrelling toward Earth, with dazzling auroras possible across the northern half of the United States over the coming nights. Minor auroral activity is ...

A violent outburst from a nearby star has given astronomers a rare, close-up look at how stellar tempers can threaten the habitability of surrounding planets. The event, a powerful solar storm ...

The planet is experiencing the most powerful solar event since 2003—and it's bringing spectacular Northern Lights.

Active areas of the sun blasted waves of charged particles, known as coronal mass ejections (CME), toward Earth this week, with two arriving on Tuesday. The result was a Severe (G4) Geomagnetic Storm, ...

Solar physicists say they have found a key source of intense gamma rays unleashed when Earth's nearest star produces its most violent eruptions. In findings published in Nature Astronomy, scientists ...

The paper suggests that solar flares disrupt Earth's magnetic field, which, in turn, causes changes in the upper atmosphere.
