What about these crashing into the sun?

[link to news.yahoo.com]

the past 15 years, more than 1,400 of these dirty snowballs have been detected, likely originating from a giant parent comet 20 to 100 kilometers wide (12 to 62 miles) that broke apart as recently as 2,500 years ago. However, until now, none of the telescopes trained on the sun was sensitive enough to follow any of these comets to their demise in the sun's atmosphere.
