Waves of colorful northern lights are expected to light up Colorado skies once again Wednesday night as severe geomagnetic storms continue, according to space weather forecasts.

A powerful geomagnetic solar storm is helping to unveil northern lights across the United States. Here's how auroras become visible.

Astronomers have for the first time detected a coronal mass ejection from another star, shedding light on worlds orbiting red dwarfs.

A rare “cannibal solar storm” is expected to hit Earth on Thursday, potentially disrupting the power grid. The phenomenon occurs when multiple bursts of solar energy occur and one wave absorbs another, and could lead to intense geomagnetic activity that could knock out GPS and communication systems.

The Sun recently erupted with its most powerful solar flare of 2025, a massive burst of energy that immediately impacted Earth’s atmosphere, leading to widespread radio blackouts across parts of Africa and Europe, as reported by Space.com. This event marks another sign that the Sun is heating up as it nears the peak of its powerful solar cycle.

Largest Solar Flare of 2025 causes radio blackouts across Europe and Africa. NOAA warns of a G3 storm that could affect power grids and GPS systems.

NOAA forecasters warn of severe geomagnetic storms reaching Earth Tuesday night, potentially affecting technology while creating spectacular aurora displays.
