Calm expected from the sun by Barazesh, Solmaz / Science News The Sun ordinarily gives some warning when it is about to let loose a coronal mass ejection (CME). Space probe captures stealth storm eruption from Sun by Balochistan Times (Baluchistan Province, Pakistan) Then, ironically, a few weeks ago, that was swept off the scare-o-meter with a Nasa report warning that, in 2012, the world could be hit by a massive plasma ball or, as they say in the trade, coronal mass ejection.
