surface mass ejection
A surface mass ejection (SME), depicted in this illustration, is a relatively recently discovered phenomenon in stellar astrophysics. They are similar to coronal mass ejections but on a far larger scale. During an SME, a star can release hundreds of billions of times more material than a coronal event, equivalent to the mass of a small planet. This was first observed in the red supergiant Betelgeuse in the constellation of Orion., by MARK GARLICK/SCIENCE PHOTO LIBRARY
