Space weather experts warn that a "strong" geomagnetic storm will rock Earth on Sept. 1-2, potentially lighting the skies ...

Particles within solar flares may reach temperatures more than six times higher than scientists previously believed—offering an explanation to a long-standing astrophysical puzzle about the Sun.

The sun has been busy lately, with solar flares and winds directed at Earth. But were they responsible for Thursday's widespread cellphone outages?

Increased solar activity could cause auroras as far south as Alabama and Northern California, but may disrupt communications on Earth tonight and over the weekend.

Why It Matters: The recent solar activity has not only sparked scientific interest but has also had real-world impacts. The ongoing solar storm has affected SpaceX satellites, according to Elon Musk.

The sun’s activity follows an 11-year cycle, known as the solar cycle, which involves phases of intense solar activity. The peak of this cycle, referred to as solar maximum, has long been ...

NOAA’s Space Weather Prediction Center in Boulder monitors the sun to protect the technology behind modern society.

After a series of recent solar storms, residents of a number of northern US states may be able to see the stunning Northern Lights this week.

A year ago this weekend, the sun’s activity created some of the most spectacular auroras on record, with displays visible as far south as Florida. This solar cycle still has the potential to ...

Fast solar wind from a massive coronal hole in the sun could trigger dazzling auroral displays as geomagnetic activity is predicted to ramp up again over the weekend.

Some states in the northern U.S. might have an opportunity to see the northern lights Tuesday, and recent solar activity may make the phenomenon visible in more states later this week, according ...

For this alone, the present 11-year solar cycle will be remarkable, whatever further activity is in store during the next two or three years that should include the peak of spot-frequency of the ...
