coronal mass ejection

Astronomers have spotted an alien planet orbiting so closely to its home star, the planet's magnetic field is triggering massive solar flares to erupt. This is the first time a planet has been seen influencing its host star.

Researchers have provided some new insights about the powerful geomagnetic storm that flared up last Mother's Day, after a big solar storm hit Earth.

A first-of a-kind space weather "tabletop" exercise has revealed major weaknesses in America's preparedness for major solar storms.

Solar eruptions created a northern lights display in North America and Europe overnight, with more auroras expected through Thursday.

A powerful X1.1-class solar flare was released by the sun on March 28, resulting in radio blackouts across North and South America

Images captured by NASA's Solar Dynamics Observatory have revealed that "coronal loops" give off subtle flashes of ultraviolet light before a solar flare, which could act as an early warning system for dangerous space weather.

A solar explosion called a coronal mass ejection is poised to graze Earth on Friday or Saturday (Jan. 24 or Jan. 25), potentially triggering colorful auroras over the northern U.S.

There were significantly more X-class solar flares in 2024 than any other year for at least three decades. The arrival of solar maximum was a key reason for the spike, but other factors were also at play.

NASA's LEXI instrument is set to land on the moon's surface sometime this month. Using X-ray sensors, the device will watch Earth's atmosphere "breathing out and breathing in" to uncover key space weather mysteries.
