Sunspot AR3842 erupted with an X7.1-class solar flare. NASA models predict that the coronal mass ejection created by the ...

A small but mighty cluster of sunspots have made their biggest mark yet on Earth's magnetosphere—and on the radio signals ...

In this instance, with such an intense amount of ultraviolet (UV) radiation that accompanied the flare, a shortwave radio ...

NASA's Solar Dynamics Observatory captured an X2.3 solar flare on November 6th, 2024, causing shortwave radio blackouts in ...

The flare was intense enough to potentially disrupt radio signals, navigation systems, and power grids on Earth.

First Imagery from GOES-19 SUVI Instrument The Solar Ultraviolet Imager (SUVI) onboard NOAA’s GOES-19 satellite (launched on ...

Solar flares are not directly responsible for the aurora borealis. The lights are caused by a phenomenon known as coronal ...

Are the Northern Lights dangerous? Solar storms in May and October saw intense displays of aurora borealis across the U.S.

Now that the sun has reached its solar maximum, aurora chasers should expect the northern lights to appear more frequently in ...

More powerful solar flares are more common during the sun's ... which is thought to have released more power than millions of the largest nuclear bomb ever exploded on Earth," Woodward said.

As the solar cycle reaches its zenith, solar flares, solar system's largest explosive events, increase, which causes phenomena such as May's solar storm, the largest observed by NASA in decades.

The sun just erupted with a powerful X-class solar flare, causing radio blackouts across the Atlantic Ocean. The flare, which hit X2.3-class in strength, was emitted at 8:40 a.m. ET from a sunspot ...
