We know that the sun has entered its peak phase of activity, called solar maximum. But are we still in it, or is solar maximum already behind us? Let's see what the data has to say. However, the ...

The unexpected surge of solar activity during the ongoing solar maximum may be tied to a lesser-known, 100-year-long cycle that is just beginning to ramp up again, a new study suggests. If that's true ...

Scientists have analyzed more than 40 years of astronomical data to uncover evidence that the sun's internal structure subtly changes from one solar cycle minimum to the next. Publishing their ...

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, ...

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 ...

As Solar Cycle 25 peaks, learn how increased sunspots and ionospheric ionization are boosting shortwave radio propagation.

The report pointed out that the sun’s energy output changes over multiple time scales, however, the most regular solar activity pattern, and the most important to humans, is an 11-year cycle of ...
