Astronomers have detected the radio burst from a massive eruption known as a coronal mass ejection (CME) on an M-type star 133 light-years away. CMEs have been suspected to occur on other stars based on activity that frequently accompanies them on the Sun, but this is the first direct evidence. Unfortunately, the major advance for stellar research makes it unlikely that planets in this star’s habitable zone could have atmospheres, and the same may be true for similar stars.

The skies across North America lit up with auroras last night, and more is to come, thanks to a series of CMEs released by the Sun earlier this week . CMEs are bursts of magnetized plasma ejected from the Sun's helio
