What is the relationship between a star’s magnetic field and its space weather, specifically coronal mass ejections (CMEs)? This is what a recent study published in Physical Review Letters hopes to ...

Most days, you can look up and see the Sun shining above. Even if it’s hidden behind clouds, you know it’s there, lighting up the sky. But while the Sun’s light might be relatively constant, its ...

Referred to as a “stealth storm,” a recent coronal mass ejection went undetected until it hit Earth. Stealth coronal mass ejections are more common after the Sun transitions from the solar maximum to ...

A strong magnetic field can disrupt a star’s ability to produce the fountains of matter called coronal mass ejections.

The sun is frequently ejecting huge masses of plasma, called coronal mass ejections (CMEs), into space. They often occur together with sudden brightenings called flares, and sometimes extend far ...

A physics team led by the University of Iowa has described a “super expanded” magnetic cloud created by a coronal mass ejection on the sun. The cloud’s dimensions were captured in two intervals of ...

Tonight, skywatchers across the U.S. have a rare opportunity to witness the northern lights that may glow far beyond their typical Arctic territory. Forecasters report that an unusual combination of ...

Why coronal mass ejections and late-cycle flares pose surprise threats to modern tech Illustrative image. When the CMEs (coronal mass ejection) slam into Earth's magnetosphere, they can create ...
