A solar cycle is a roughly 11-year periodic change in the Sun characterized by variations in the number and intensity of sunspots, as well as a flipping of its magnetic poles.

A new paper calculated a solar storm could bring down the planet's satellite system in just three days, wreaking havoc on ...

Every day on Earth, you experience weather. You feel the wind blowing and see clouds move across the sky. Sometimes there are ...

A new study warns that massive solar storms could trigger a catastrophic chain of satellite collisions in low-Earth orbit ...

Our sun continues to make news headlines as we’re still in a strong solar cycle that has generated numerous solar flares and coronal mass ejections (CMEs). CMEs are a large release of plasma and ...

A new study finds that, with the immense quantity of satellites that hurtle in Earth's orbit today, the first smashup would ...

NASA's Solar Dynamics Observatory captured a massive 'tornado' on the sun in multiple wavelengths. Unlike the Earth, ...

The Sun exhibited unpredictable behavior with two strong solar flares in late November and early December 2025. These events, captured by NASA's Solar ...

A new study warns that a major solar storm could disable satellite controls and trigger cascading collisions in low Earth ...

A powerful M8.1 solar flare sent a full-halo coronal mass ejection toward Earth, and scientists expect it to trigger strong G3 geomagnetic storm levels on Tuesday. Forecasts show the Kp index rising ...

Aditya-L1 and U.S. satellites uncover why the May 2024 solar storm behaved unusually, revealing significant magnetic field dynamics.
