See the sharpest views yet of the sun's corona — from coronal rain to a never-before-seen plasma stream racing along the sun at incredible speeds.

Coronal rain forms when hotter plasma in the sun’s corona cools down and becomes denser. Because the plasma is electrically charged, it follows the magnetic field lines, which make huge arches ...

SEATTLE — Although there may still be some residual geomagnetic activity from a coronal mass ejection that hit Earth's atmosphere over the weekend, it's unlikely to result in visible northern ...

By Monday night, the likelihood of being able to see the northern lights in Chicago drops considerably. The geomagnetic storm comes from a coronal mass ejection passing over Earth and other ...

While Sunday had a higher likelihood of visibility, another coronal mass ejection is set to strike late on June 2. Here's what to expect for Monday night. Are the Northern Lights visible in Missouri?

The northern lights — also called aurora borealis — could be visible in Alaska, Washington, Montana, North Dakota, Minnesota, Michigan, Maine, northern parts of Idaho, Wyoming, Iowa, New York ...

People using GLP-1 drugs like Ozempic are reporting "Ozempic teeth," an unusual side effect impacting dental health. "Ozempic teeth" may involve tooth decay, sensitivity, and tooth loss. Dentists ...

Coronal rain forms when hotter plasma in the Sun’s corona cools down and becomes denser. Like raindrops on Earth, coronal rain is pulled down to the surface by gravity. Because the plasma is ...
