NASA’s SOHO (Solar and Heliospheric Observatory) captured a comet plunging to a fiery death into the Sun on May 10-11, 2011. In the video, the Sun covered by the red disk, and the white circle represents the Sun. The explosion that occurs as the comet approaches the Sun is thought to be a coronal mass ejection that just happened fortuitiously at about the same time and is not directly caused by the comet hitting the Sun. Analysis of this explosion shows that the ejection erupted before the comet came close enough to the solar surface to interact with strong magnetic fields.
