Space Weather

A powerful solar flare knocked out radio communications on Earth last night in what space weather forecasters fear might be the beginning of a spell of rough space weather in the coming days.

A stealthy solar storm surprised forecasters, causing spaceflight delays and incredible aurora displays as far south as New Mexico.

A 'hole' in the sun's upper atmosphere may soon generate another geomagnetic storm here on Earth, creating auroras in places farther from the poles than usual.

NASA's Solar Dynamics Observatory captured what might be 'the tallest tornado' in the solar system swirling across the north pole of the sun.

The powerful solar storm that struck Earth earlier this week treated an American astrophotographer to unexpected aurora displays during a shooting trip to California's Death Valley.

A solar storm that swept across Earth on Monday (Feb. 27) forced SpaceX to delay a Starlink launch and temporarily disrupted operations of several Canadian oil rigs.

The sun recently spat out an X-class solar flare, one of the most powerful it can emit, which triggered a rare shockwave across the sun's surface and caused radio blackouts on Earth.

A massive solar flare erupted from the sun on Friday (Feb. 17) as the Earth was under a geomagnetic storm watch from flares earlier in the week.

The acoustically generated force will help astronomers better understand the sun's photosphere and the causes of space weather.

A major solar flare erupted from the erupted from the sun on Saturday (Feb. 11) and a NASA spacecraft caught it on video.

The tiny sun used sound waves to simulate the sun's swirling mass of plasma

Magnetic properties of coronal holes in the sun's atmosphere can help forecast the severity of geomagnetic storms that hit Earth.

An image taken by an Austrian comet hunter reveals a disconnection in Comet's C/2022 E3 (ZTF) tail that may have been caused by turbulent space weather.

When solar winds bombard Earth's magnetosphere, they create waves that shouldn't be able to traverse a turbulent region called the shock. New research demonstrates how this appears to happen.

A new time-lapse image shows two major sunspot groups moving across the surface of the sun in December 2022, when the number of solar splotches also skyrocketed to an eight-year high.

The sun has fired off its third powerful X-class solar flare in less than a week, scoring an explosive hat trick.

A new NASA video reveals the ever-changing surface of the sun in a stunning time-lapse that spans 133 days.

A massive explosion on the sun unleashed a powerful solar flare from a new sunspot on Monday (Jan. 9), one that is slowly turning to face the Earth.

A newly emerged sunspot is making its presence known, unleashing a powerful X-class solar flare that triggered shortwave radio blackouts across the South Pacific.

A giant cloud of magnetized plasma exploded from a sunspot hidden on the far side of the sun, which might turn to face Earth only two days from now.
