Aurora chasers are on high alert for geomagnetic storm conditions overnight with northern lights possible at mid-latitudes.

The Sun's activity typically peaks at solar maximum, but there's an even more dangerous stage it could enter, and with potentially dire consequences.

A winter storm system dumped heavy snow and freezing rain across the eastern United States on Monday, disrupting travel for millions after bringing hazardous road conditions in the Midwest that ...

An international team, including an Oregon State University astrophysicist, has confirmed a 19-year-old theory on solar flare formation by observing “slip-running” reconnections of the sun’s magnetic ...

The observation was made using NASA’s Solar Dynamics Observatory (SDO), a satellite dedicated to monitoring the Sun’s activity ... Scientists are eager to study the planet’s magnetic field, surface ...

The Sun periodically ejects huge bubbles of plasma from its surface that contain an intense magnetic field. These events are called coronal mass ejections, or CMEs. When two of these ejections collide ...

The clearest and most precise images yet of the universe in its infancy—the earliest cosmic time accessible to humans—have ...

Still, sun-watching spacecraft caught impressive views of the ejection as it blasted plasma and magnetic field into space. When a CME occurs, plumes of plasma and the sun's magnetic field are ...
