The aurora is expected to be bright and visible in multiple northern U.S. states Oct. 3 through Oct. 5 as well as from the lower Midwest to Oregon.

There were significantly more X-class solar flares in 2024 than any other year for at least three decades. The arrival of ...

At the start of this new year, we look back at close-up pictures and solar flare data recorded by the ESA-led Solar Orbiter ...

Using NASA’s Solar Dynamics Observatory, scientists have identified flickering loops in the solar atmosphere, or corona, that ...

one team has identified flickering loops in the solar atmosphere (corona) that seem to signal when the sun is about to unleash a large flare. These warning signs could help NASA and other ...

A powerful X1.8 solar flare erupted on January 4, 2025, and was recorded at its peak—7:48 a.m. ET—by NOAA’s Solar Ultraviolet ...

That is the highest total since at least 1996, when this dataset began. NASA has been tracking solar flare activity since the mid-1970s, but earlier data has not been made publicly available and ...
