The Sun Is Vomiting Iron

A series of solar eclipses – on 2006, 2008 and 2009 – have allowed scientists to take these beautiful images of the Sun’s corona, the first ones in history that show a phenomenon called the Iron Line.

The Iron Line is made of highly ionised iron, called Fe XI 789.2 nm. The iron spewing reaches an extremely far distance – an amazing three times the solar radii – and has regions in which there are more irons than in others. [NASA]
