The Solar Cycle. Much of the Sun's tempestuous nature comes from its core. At its core is dense, electrically charged gas. ... About every 11 years, the Sun's magnetic field does a flip.

As we approach solar maximum, something strange is happening to the sun's magnetic field. We explore this flip in polarity in more detail and look at the effects it could have on Earth.

The sun's magnetic field originates much closer to the surface than previously thought, according to new research. The finding could help predict periods of solar storms.

New research indicates the sun's magnetic field originates much closer to the surface than previously thought, a finding that could help predict extreme solar storms.

The sun’s solar activity reaches its peak at the middle of this cycle. According to NASA, the sun’s excess solar flares and winds wreak havoc on the Earth’s magnetic field.

The sun has a powerful magnetic field that creates sunspots on the star’s surface and unleashes solar storms such as the one that bathed much of the planet in beautiful auroras this month.. But ...

The most active cycle ever recorded—as measured by the highest sunspot count at solar maximum—was Cycle 19, which spanned the period between April 1954 and October 1964.

This magnetic cycle lasts approximately 22 years, through which the sun's magnetic field reverses and then reverts to its original state, Ryan French, a solar astrophysicist and Space.com ...

Known as the Hale cycle, this magnetic cycle lasts approximately 22 years, through which the sun's magnetic field reverses and then reverts to its original state, Ryan French, a solar ...
