An astronomer in Slovakia captured the rare luminous phenomenon as it briefly flashed in Earth's upper atmosphere during a thunderstorm.

India is setting its sights on the sun after its successful moon landing. The Aditya-L1 spacecraft will investigate the mysteries of our star following its launch on Sept. 2.

The sun has launched a surprise coronal mass ejection directly at Mars, which could spark auroras on the Red Planet and potentially erode part of Mars' remaining atmosphere when it hits on Sept. 1.

NASA's Perseverance Mars rover has captured photos of a big sunspot, which should rotate into view for those of us on Earth in the coming days.

"It's why we never throw anything away – you don't know what secrets are being stored in the data beamed down from space."

Mild solar storms can cause more serious problems to GPS satellites than once-in-a-century events, a new study has found.

A powerful solar flare disrupted radio and navigation signals across North America on Monday and prompted space weather forecasters to issue warnings because of energetic particles hitting Earth.

In 2021, a coronal mass ejection that erupted from the sun was seen across a staggering range of 155 million miles. It spit energetic particles toward Mars, the Earth and the moon.

A new space weather sensor is heading to the International Space Station to help scientists understand how the sun's outbursts alter Earth's upper atmosphere.

The way in which the radiant displays of colors in the sky known as auroras form on Earth may be how these lights arise throughout the solar system, according to new findings from Mercury.

Two coronal mass ejections have combined into an enormous cloud of magnetized plasma that is forecast to hit Earth on Tuesday and potentially trigger a strong geomagnetic storm.

A new video shows off the sun's incredible power. A 'solar tornado' erupted from the surface in April, and you can watch it in 4K resolution.

As the U.S. celebrated July 4, the sun hosted its own fireworks display in the form of a coronal mass ejection "double punch" that NASA predicts could strike Earth on Friday (July 7).

The giant sunspot AR3354 blasted out an X-class solar flare on Sunday, July 2, ionizing Earth's atmosphere and causing a shortwave radio blackout over the U.S. and the Pacific Ocean.

The sun has produced 163 sunspots in June, the highest monthly number in more than two decades, sparking concerns that Earth may soon face space weather trouble.

Neutral particles accelerated to incredible speeds could be used to investigate powerful solar storms, according to a new study.

A massive new sunspot is visible without using a telescope or binoculars, but you'll still need to protect your eyes when observing it.

The world's largest solar telescope has captured the sun's fine features in remarkable detail, including rare glimpses of dying sunspots.

The sun has released a barrage of solar flares in the past 24 hours. The culprit? A giant sunspot that's slowly rotating to directly face Earth — and it's not alone.

A pair of eruptions seen on the sun might lead to a display of auroras for parts of the northern and central United States on May 11.
