Side-by-Side Solar Eruptions
Coronal Mass Ejection on the Sun.

Two coronal mass ejections (CMEs) expand side-by-side from the Sun and out into space in this movie, playing out in front of the ESA/NASA Solar and Heliospheric Observatory, SOHO, on 1-2 July 2013.
The shaded disc at the centre of the image is a mask in SOHO’s LASCO instrument that blots out direct sunlight to allow study of the faint details in the Sun’s corona. The white circle added within the disc shows the size and position of the visible Sun.
