Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…

An asteroid discovered more than 100 years ago my not be an asteroid at all, but an extinct comet that is coming back to life, according to new observations.The night of Dec. 11, Steve Larson, senior staff scientist with the Catalina Sky Survey, was searching for potentially hazardous asteroids when he came across what looked like a comet: a faint, wispy tail surrounding a bright, star-like core. Four images taken over the course of 30 minutes revealed the object was moving relative to the background stars….
