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.

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

The rapid growth of satellite mega-constellations, such as SpaceX’s Starlink, has revolutionized global communication.

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 University of Michigan study offers one of the most detailed pictures so far of how violent sun storms spread across space — and occasionally, straight to our planet. With the help of ...

The rapidly growing traffic of satellites in low Earth orbit is increasingly becoming vulnerable to space weather events and ...

A predictive space weather model developed by APL and partners that is designed to simulate how solar storms affect Earth is now widely available to researchers and the broader public.

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

Activity on the sun is not constant; it varies along a cycle of about 11 years. The peak of this solar cycle — called solar maximum — is when sunspots, solar flares and coronal mass ejections (CMEs) ...

Powerful waves unleashed by solar storms could be the key to understanding extreme radiation. (SwRI) researchers now think they have found the answer to a puzzle that has lingered for nearly four ...
