Satellites would likely begin colliding with each other or space junk in less than three days if they were to lose the ...

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 ...

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

Solar activity could cause stronger-than-usual auroras, making the northern lights visible in more U.S. regions than usual.

"A single collision could have catastrophic long-term consequences," the authors explain, and we would not have long to avoid ...

Location signals beamed to Earth by GPS satellites were off by hundreds of feet during the Gannon Solar Storm in May last year, and the disruption lasted for up to two days in some U.S. regions, a new ...

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 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 ...

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

The Sun exhibited unpredictable behavior with two strong solar flares in late November and early December 2025. These events, ...

The European Space Agency's Swarm mission detected a large but temporary spike of high-energy protons at Earth's poles during ...
