Astronomers have confirmed the first observation of a coronal mass ejection (CME) from a star other than the Sun, using ESA's XMM-Newton and LOFAR telescopes. The CME, originating from a red dwarf star 130 light-years away, was extremely fast and dense, capable of stripping away planetary atmospheres, which has significant implications for the habitability of planets orbiting active stars.

A severe geomagnetic storm watch has been issued for the U.S. due to multiple coronal mass ejections from the sun, with the strongest expected to hit Earth on November 12, 2025. This could lead to spectacular northern lights visible as far south as Alabama and California, but also poses a risk to critical technology infrastructure. The storm's intensity is classified as G4, a rare level, and observers are encouraged to find dark skies for a chance to see the auroras.
