footage of the solar corona during three explosions
Images taken on 21 October 2010 by the SDO (Solar Dynamics Observatory) space telescope launched on 11 February 2010 by NASA to study the Sun. False colors represent images taken with different filters, sensitive to different temperatures of the solar crown: blue indicates 1,000 ° C; green 1,500 ° C; red 2,000 ° C. The video shows three simultaneous explosions: one near the center of the disc and two on opposite sides of the Sun. Together they cover over 1,600,000 km.
The video was processed using material from NASA, the American space agency.
