In a historic first, astronomers observe massive solar eruption on nearby star
For the first time ever, astronomers have observed a coronal mass ejection (CME) coming from a star that isn’t our Sun. CMEs are massive eruptions we often observe coming from the Sun. They drive space weather and are responsible for phenomena such as the auroras we see near the Earth’s poles.
A powerful solar eruption from sunspot AR4274 triggered a massive X5.1-class solar flare, causing a Ground Level Event (GLE) with energetic protons re
Astronomers observed a massive, multi-temperature plasma eruption from a young Sun-like star, revealing how early solar explosions could shape planets. These fierce events may have influenced the atmosphere and life-forming chemistry of the early Earth.
At about 0200 UTC (that’s 1pm AEDT) on November 12, the US National Oceanic and Atmospheric Administration and Australian Bureau of Meteorology reported large disturbances in Earth’s magnetic field due to the solar eruptions: a G4, or severe, geomagnetic storm.

Sun unleashes 2 colossal X-class solar flares, knocking out radio signals across the Americas and Pacific
The back-to-back eruptions caused radio blackouts across two hemispheres as the active sunspots turn to face Earth.
A coronal mass ejection happens when an enormous cloud of charged and highly magnetised plasma erupts from the solar corona into space, causing radio and magnetic disturbances on Earth. The Northern Lights, also called the aurora borealis, are typically only visible from northern latitudes.
Largest Solar Flare of 2025 causes radio blackouts across Europe and Africa. NOAA warns of a G3 storm that could affect power grids and GPS systems.
A strong geomagnetic storm (G3) is unfolding as Earth is hit by multiple solar eruptions and fast solar wind, creating ideal conditions for the northern lights to appear again tonight The storm was triggered by a coronal mass ejection (CME) from a solar flare on Nov.
