Comets are extending life of galaxies. Due to their unusual move, they are helpig to keep the delicate relations between planets, stars, suns etc. in a special dynamic balance. Comets are not harming, a man is afraid because of not understanding of complicated plan of the Universe. A man should never cause a damage to a comet nor try to attache anything to it or install anything in/on it. A comet never loses it's tail to the end, even if we cannot see it. Turn attention that the comet do not provokes cosmic catastrophes on her long way, though we think that way should be accidental.
