Sunspot AR3184 erupted with an X1.9-class solar flare on Jan. 9, 2022. NASA's Solar Dynamics Observatory (SDO) captured the fireworks. The sunspot has been very active since it rotated into SDO's view ...

It is described as "the most powerful particle accelerator in the solar system," a statement that has never been more accurate. The particle flows released during solar flares and CMEs far exceed ...

The hottest parts of the sun are its solar flares, and a new study suggests these flares could be more than six times hotter ...

The star at the center of the solar system does more than provide light and warmth. It also acts as the most powerful particle accelerator in the neighborhood, whipping electrons to near-light speed ...

Beautiful yet dangerous solar flares that erupt from the sun could be as hot as 180 million degrees Fahrenheit, researchers say. That's more than six times hotter than solar physicists previously ...

Solar flares are intense bursts of light and particles from the sun. While they can pose hazards for things like satellites, these flares are also beautiful, dramatic and incredibly hot. NPR's Nell ...

Solar flares can be many times the size of Earth and can damage things like satellites. A new study suggests that eruptions from the sun can be even hotter than researchers thought. KUOW is Seattle’s ...
