The ongoing Solar Cycle 25 began in 2019 with a quieter Sun and is predicted to end around 2030. A solar cycle is roughly an 11-year period of the Sun's magnetic activity, from quiet (minimum) to ...

The sun is governed by a strict rhythm. The magnetic activity of the sun displays a cyclic variation, reaching a maximum approximately every eleven years. Two enormous plasma circulations, each in one ...

When you look up at the sky on a sunny day, the sun might seem like a bright spot, unchanging in the sky. But the sun is a complex, dynamic celestial body, wrapped in electrical currents and magnetic ...

On December 8, 2025, the Sun unleashed a powerful solar flare, an event that captivated the attention of scientists and space enthusiasts alike. This flare, classified as an X1.1, marks one of the ...

The regular solar cycle is a mere climate murmur, but sudden geomagnetic jolts are a different story. These high-altitude outbursts appear to be hijacking the polar vortex to rewrite weather on the ...
