A 'Cannibal' plasma eruption from the sun will hit Earth on Dec. 1. Scientists predict strong geomagnetic storm conditions and impressive auroras.

Stay up-to-date with the latest news on the total solar eclipse on April 8, 2024.

Several powerful solar eruptions, with Earth in the firing line, means widespread mid-latitude aurora displays are likely on Nov. 30 and Dec. 1.

India's newly launched Aditya-L1 sun-studying mission has already captured its first glimpse of a solar flare in high-energy X-rays.

Space is a dangerous place, especially when it comes to high-energy particles, and intense solar activity can pose threats to people and technology on Earth.

A network of eight satellites in low-Earth orbit can gather unique measurements about space weather to help with space debris.

Scientists have discovered the most powerful solar storm ever recorded using ancient tree rings from the French Alps.

New research indicates that the number of migrating birds decreases during severe space weather events. They are also more prone to becoming lost.

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.
