Mercury Framed by a Coronal Mass Ejection

A Coronal Mass Ejection (CME) from the Sun frames Mercury, as observed by the SOlar Heliospheric Observatory (SOHO) on 13 August 2014.

The shaded blue disc surrounding the Sun at the center is a mask in SOHO’s LASCO instrument that blots out direct sunlight to allow study of the details in the Sun’s corona.
