Geomagnetic storm triggers auroras in Mexico
Raportoinut AI AI:n luoma kuva
A severe geomagnetic storm, triggered by a solar coronal mass ejection, lit up the skies with auroras borealis in Mexico and the northern hemisphere on November 11, 2025. Images of green and purple colors were captured in states like Zacatecas and Nuevo León, while in the United States they were seen in Colorado and Kansas. UNAM and NOAA experts indicate that effects will continue more faintly on November 12 and possibly on the 13th.
Scientists have achieved a milestone in solar observation by tracking an exceptionally active region on the Sun, NOAA 13664, almost continuously for 94 days using data from two spacecraft. This region, which emerged in April 2024, triggered the strongest geomagnetic storms since 2003 and caused widespread auroras. The extended monitoring reveals how complex magnetic fields drive solar storms with real-world impacts.

Scientists using the LOFAR radio telescope and ESA's XMM-Newton observatory have detected the first confirmed coronal mass ejection from a star other than the Sun. The eruption, from a red dwarf 130 light-years away, traveled at 2400 km per second and could strip atmospheres from nearby planets. This discovery has significant implications for the habitability of exoplanets around such stars.
