A colossal coronal hole, nearly 500,000 miles (800,000 kilometers) wide, has opened in the sun's atmosphere, spewing fast-moving solar wind toward Earth. Coronal holes are regions where the sun's ...

The wind is billowing out of a hole in the sun's upper atmosphere ... night's aurora forecast. NOAA Coronal holes form in the outermost layer of the sun when the local magnetic field opens ...

These dark areas on the Sun, as seen in satellite images, can produce space weather events known as coronal hole high-speed streams (CH HSS), which can trigger Northern Lights on Earth.

A massive hole ... Sun's atmosphere—and it could lead to aurora over the U.S. NASA captured a photograph of the roughly 497,000-mile-wide phenomenon—an example of what physicists call a ...

The high-speed solar wind originating from this coronal hole, imaged here on Oct. 10, 2015, by NASA's Solar Dynamics Observatory, created a geomagnetic storm near Earth that resulted in several ...

NOAA Space Weather Prediction Center Service Coordinator Shawn Dahl joins FOX Weather to explains what coronal holes on the Sun can mean for space weather impacts on Earth. These areas of less ...

A giant hole about the size of 60 Earths has opened up in the Sun's atmosphere, scientists say. The dark area is known as a coronal hole and can be found on the outermost region of the Sun's ...

Forecasters said a coronal hole high-speed stream—winds from a cooler, less dense area on the sun’s surface—will likely result in a geomagnetic storm later Friday, marking a disturbance in ...

It indicates that the aurora may occur halfway between the green and yellow lines in the below image: These solar winds are coming from a giant coronal hole on the sun. The giant dark spot is not ...
