Sunspot AR3256 erupted with an X1.2-class solar flare. NASA's Solar Dynamics Observatory captured the fireworks in multiple ...

The sun is putting on a show. On Sunday the star unleashed several strong and bright solar flares, including one of the most powerful eruptions seen in decades. Far from the steadily glowing orb we ...

This Feb. 4, 2026, image from NASA's Solar Dynamics Observatory (SDO) captures a strong solar flare erupting from the star.

NASA explained that the flares and solar eruptions can impact radio communications, electric power grids, and navigation signals.

New research by Southwest Research Institute (SwRI) and the National Science Foundation's National Center for Atmospheric Research (NSF-NCAR) has developed a new tool providing a first step toward the ...

This week, we examine strength from different perspectives. The energetic strength of a solar flare and its effect on Earth. The gravitational strength of dark matter in our universe and its ...

A team led by Shadia Habbal at the Institute for Astronomy — drawing on more than a decade of eclipse observations — for the first time clearly identified turbulent structures in the sun’s corona, ...

NASA captured an image of an intense solar flare released by the sun on Tuesday evening. The solar flare peaked at 5:49 p.m. EDT on Tuesday, NASA's Solar Dynamics Observatory said. It was an X-class ...

The $850 million Solar Dynamics Observatory may help scientists find the causes of solar weather events that disrupt technologies on Earth—while taking unprecedented high-resolution pictures of the ...

A new sunspot group has quickly grown and is spewing out the most intense type of solar flare. Effects on Earth are forecast to be limited.
