The massive sunspot that sparked an "extreme" geomagnetic storm in May 2024 unleashed hundreds of other dangerous solar ...

On Aug. 8, scientists may have caught hundreds of individual sunspots on images produced by NASA's Solar Dynamics Observatory (SDO). "The process of the solar cycle, the 11-year (on average) dynamic ...

A whopping sunspot that is getting larger and crackling with activity threatens to flash powerful solar flares in our planet's direction. The sunspot, named AR3780, appears to be getting bigger and ...

The agencies that track sunspot activity say we’re now in peak solar activity, which has a big impact on the amount and southward extent of the Northern Lights. On Oct. 15, 2024 NOAA, NASA and the ...

Our sun has officially hit its solar maximum, with increased rates of auroras and solar flares expected in the coming months, NASA has announced. The sun goes through 11-year cycles of activity, ...

The sun is powered by the nuclear fusion of hydrogen to helium, deep within its core. Above the sun's surface, however, a different force dominates: electromagnetism. This force is responsible for ...

Sunspots are the visible component of active regions, areas of intense and complex magnetic fields on the Sun that are the source of solar eruptions. “During solar maximum, the number of sunspots, and ...

Observing an eclipse of the sun is always fascinating, but on March 29, 2025 — when a partial solar eclipse is visible in the Northern Hemisphere — there will be an extra reason to do so. As well as ...

On Aug. 8, NASA scientists may have spotted a record number of sunspots when hundreds of individual spots were estimated to occur within 24 hours. When you purchase through links on our site, we may ...

Images from NASA’s Solar Dynamics Observatory highlight the appearance of the Sun at solar minimum (left, Dec. 2019) versus solar maximum (right, May 2024). These images are in the 171 wavelength of ...
