On Tuesday, NOAA issued a G4, or severe, geomagnetic storm watch in response to recent coronal mass ejections, or CMEs, from the sun. CMEs are huge bubbles of coronal plasma that the sun occasionally ejects, NASA says. The highest geomagnetic storm level is G5, which is considered extreme.

Nature offers many dazzling displays, from jagged flashes of lightning to radiant sunsets. But perhaps one of the most elusive natural phenomena is the shimmering waves of green, pink, and red dancing across the night sky,

Fans who attended or watched Wednesday's MAC showdown between Toledo and Miami (Ohio) got a special treat in the third quarter.

Bands of green and red first pierced through the hazy night sky around 9:30 p.m. above the pier at Grand Haven State Park.

The northern lights were visible Tuesday night across the Chicago area, illuminating the sky with brightly colorful displays due to severe solar storms.

The Statesman collaborated with readers to gather photos of the aurora borealis throughout Central Texas. Here are the eerily beautiful results.

Coronal mass ejections, or CMEs, are large clouds of ionized gas called plasma and magnetic fields that erupt from the sun’s outer atmosphere. When these outbursts are directed at Earth, they can cause major disturbances of Earth’s magnetic field, resulting in geomagnetic storms.

The University of Alaska and Space Weather Prediction Center forecasts say the best chance of seeing the northern lights starts as early as 10 p.m. ET Tuesday and will last until around 1 a.m. Wednesday.
