A Japanese poet wrote in his diary that "red lights" appeared in the sky over Kyoto. An analysis of tree rings suggests a ...

Three coronal mass ejections fired from the sun over the past 48 hours are now racing toward Earth, and the National Oceanic ...

The sun has just released a powerful M5.7 solar flare, sending a stream of charged particles hurtling toward Earth’s ...

Inside the core, particles collide and release incredible amounts of energy, which radiate out from the Sun in the form of light – a process called nuclear fusion. The light travels outward towards ...

A team of scientists has recorded one of the most detailed views ever of a failed solar eruption, a powerful blast from the ...

A Cosmic solar flare erupted on May 10, triggering radio blackouts and a CME. It may spark possible northern lights on Earth ...

A powerful M5.7 solar flare erupted from the sun on May 10, unleashing an impressive coronal mass ejection (CME) that could ...

A solar eruption has blown a massive hole in the sun's atmosphere, causing temporary radio blackouts and possibly triggering a northern lights display tomorrow. Scientists recorded an M5.7-class solar ...

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 ...

Solar energetic particle (SEP) events and coronal mass ejections (CMEs) are central features of solar activity that significantly influence space weather. SEPs are high‐energy particles expelled ...

Artist's depiction of a coronal mass ejection from EK Draconis. The hotter and faster ejection is shown in blue, while the cooler and slower ejection is shown in red. Scientists believe that when the ...
