NASA's Interface Region Imaging Spectrograph (IRIS) mission captured an X1.1-class solar flare. See time-lapse footage of the blast that caused "a strong shortwave radio blackout over South America," ...

MORE: This is when peak northern lights activity will occur These sunspots can produce solar flares and coronal mass ejections that manifest in a dazzling light show when they reach Earth.

The first CME was released during an M-class solar flare eruption on Jan. 21 and the second from a filament eruption on Jan. 22. If both CMEs land a blow their combined result could be minor (G1 ...

Solar flares are violent outbursts of electromagnetic radiation that shoot from the sun when invisible magnetic field lines at the sun's surface get twisted up until they eventually snap. These ...

On a hot and humid Florida night in late August 1859, the sky suddenly lit up. But it was not from fireflies or a fireswamp. Instead, it was the Northern Lights–or aurora borealis. The aurora is ...

Scientists believe they’ve found a potential way to predict solar flares. Using NASA’s Solar Dynamics Observatory, a team has identified early warning signs of solar flares. This could protect ...
