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 ...

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 ...

Solar cycles, characterized by fluctuating sunspot activity, occur approximately every 11 years, although their duration varies between 8 and 14 years. The study of solar cycles dates back to the ...

The colossal ball of hot gas at the center of our solar system will be lively for the next year, NASA said. The sun has reached its "solar maximum period," which is a state of heightened activity in ...

Auroras aren't over: the sun's decline brings more storms, and a 'last gasp' finale could light up skies in the next 2 years. When you purchase through links on our site, we may earn an affiliate ...
