Arrows point out a small comet plunging into the Sun, as seen by the Solar and Heliospheric Observatory (SOHO) coronagraph, which blocks the Sun's glare. This comet traveled a distance over 30 solar radii in just over a day. Nearly all of the sungrazers observed by SOHO are members of the same group (the Kreutz group), the remains of a single, parent comet that broke up some centuries ago. SOHO has discovered over 1,300 comets, more than anyone or anything else ever has.
