KAMIKAZE COMETS: A pair of comets swung perilously close to the sun on May 24th; neither survived intact. In this SOHO coronagraph movie of the encounter, the ghostly tail of one comet continues past the sun after its icy nucleus was likely destroyed by the sun's intense heat. A smaller trailing comet vanishes entirely.
These disintegrating comets were themselves fragments of a single enormous comet that broke apart thousands of years ago. Astronomers call them "Kreutz sungrazers" after the 19th-century astronomer Heinrich Kreutz who studied them in some detail. In recent years SOHO has spotted hundreds of Kreutz sungrazers streaming toward the sun. Most of them end up as these two did: vaporized
