A team of researchers led by Costanza Argiroffi, an astronomer at the University of Palermo in Italy, has found evidence of a coronal mass ejection (CME) from a star that was not our sun—the first ever observed. They reported their findings at this year's Cool Stars 20 meeting in Massachusetts.
A coronal mass ejection occurs when a star spews a glob of plasma and charged particles from its corona into surrounding space. They quite often occur with our sun following a solar flare. In this new effort, the researchers found evidence of a CME from a large star (approximately three times the mass of the sun) called HR 9024—it is approximately 450 light-years from Earth.

Happens all the time, just most mature stars are unwilling to talk about it at conventions.
