The latest Northern Lights forecast means the aurora borealis may be seen in the continental U.S. tonight after space weather ...

A gigantic hole has opened up in the Sun's atmosphere and is currently big enough to spot from Earth. The structure located ...

NOAA classifies geomagnetic storms using a G-scale, which ranks their intensity from G1 (minor) to G5 (extreme). The recent geomagnetic storm watch NOAA issued is rated as a G1. Auroras occur when ...

The Korea Astronomy and Space Science Institute (KASI) Solar Space Environment Group observed the G5-class geomagnetic storm that occurred from May 10 to 12 of last year through the latest ...

The gigantic coronal hole is blasting high-speed solar wind toward Earth, potentially igniting vibrant auroras and minor ...

Aurora chasers are on high alert for minor geomagnetic storm conditions from Jan. 24 through to Jan. 25. Northern lights might be visible over some northern and upper Midwest states.

A massive coronal hole has opened on the sun, sending high-speed solar wind toward Earth and increasing aurora activity.

More powerful geomagnetic storms result in the northern lights being seen further towards the equator. G1 storms are the weakest class, while G5 storms are the most powerful. The G5 storm recorded ...

The solar wind escaping from this coronal hole — the diameter of which measures over 62 times that of the diameter of Earth — ...

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.
