Auroral activity is best seen between 10 p.m. and 2 a.m. local time while at a high vantage point away from light pollution, according to NOAA. If conditions are optimal, the northern lights could be seen as far as 620 miles away.

Stunning satellite imagery reveals the aftermath of a deep freeze in Chicago, showcasing ice formations on Lake Michigan and snowfall across the city.

The images were captured using NASA’s Earth Polychromatic Imaging Camera (EPIC), a 4MP CCD camera and telescope on the DSCOVR satellite

The aurora borealis is back and is expected to be visible in more than 10 states. See which states will have the best views.

The agency expects a minor or greater geomagnetic storm—a disturbance of Earth’s magnetic field—on Saturday, which increases the likelihood of northern lights displays being visible to more people, as the effects of a recent coronal mass ejection reach Earth, according to NOAA’s three-day forecast.

NASA warns of solar storms disrupting global tech, power grids, and satellites, urging upgrades, collaboration, and preparedness to protect a tech-dependent world.

Solar material is gusting out of the dark patch in the Sun's corona towards Earth at more than a million miles per hour.

Graphic visualisation of NASA's Solar Dynamics Observatory (SDO) shows a vast 500,000 mile-wide coronal hole in the sun's atmosphere.

The definition: An atmospheric river (AR) is a long plume of moisture that stretches from the tropics or subtropics into higher latitudes, often thousands of miles long. These thin ribbons of humid air can be identified and tracked in satellite imagery and computer model forecasts.

A January 2025 cold wave plunged Chicago into subzero temperatures, initially without snow. By late January, snowfall returned, and Lake Michigan’s ice formed in shifting patterns. While its ice levels stayed near average,

A decade ago, startups raising money to launch commercial weather satellites were convinced they had a goldmine on their hands because they could improve forecasting models. The problem? NOAA

The effects of a coronal mass ejection—a bubble of plasma that bursts from the sun’s surface—will likely impact Earth’s magnetic field on Saturday, bringing the northern lights to several northern U.S. states, according to the National Oceanic and Atmospheric Administration.
