When they happen, CMEs send clouds of extremely hot charged particles (aka plasma) at extremely high velocities into space. These ejections, which occur with our Sun regularly, often accompany a stellar flare (or sudden and bright burst of radiation). Their study explores a stellar phenomenon known as a "coronal mass ejection" (CME), aka. He was joined by researchers from CU Boulder's Laboratory for Atmospheric and Space Physics (LASP), the Nishi-Harima Astronomical Observatory (NHAO), the Tokyo Institute of Technology, the Graduate School of Advanced Integrated Studies in Human Survivability, and multiple universities. Kosuke Namekata, a researcher at Kyoto University, the National Astronomical Observatory of Japan (NAOJ) and the National Solar Observatory (NSO).
The study, which appeared in the December 9th issue of the journal Nature Astronomy, was led by Dr. These observations suggest that these ejections can worsen over time, which could be a dire warning for life here on Earth.
While observing EK Draconis, a G1.5V yellow dwarf located 110.71 light-years away, an international team of astronomers witnessed a massive coronal mass ejection that dwarfed anything we've ever seen in our Solar System. Even if a star has multiple planets orbiting within its habitable zone (HZ), the tendency to periodically flare could render these planets completely uninhabitable.Īccording to a new study, stars like our own may not be as stable as previously thought.
