Astronomers detected the first confirmed CME from a star beyond our solar system, a powerful explosion from a red dwarf 130 light-years away that could strip exoplanet atmospheres.
Astronomers have detected the first confirmed coronal mass ejection (CME) from a star beyond our solar system, a red dwarf named StKM 1-1262, located 130 light-years away.
The explosion, traveling at 5.3 million mph, was 10,000 to 100,000 times stronger than the most powerful solar CMEs and could strip atmospheres from nearby planets.
Detected via a type II radio burst using the LOFAR telescope and analyzed with new RIMS software, the event revealed a high-speed plasma outflow.
The findings, published in Nature, mark a breakthrough in studying extrasolar space weather and its impact on exoplanet habitability.
