肉眼看到彗星的机会很少,尤其是长尾巴的亮彗星更是罕见,因此彗星有重要的观测研究意义.艾森(ISON)彗星无疑是2013年最新奇的天象之一,它是从太阳系边缘初次到太阳系内区被发现的"新"彗星,曾推测它走近地球时可能展示"世纪彗星"的壮观丰姿,又穿越太阳外部的高温大气(日冕)而展现"飞蛾扑火"的"掠日彗星"毁灭闹剧.从天文爱好者到专家及太空飞船做了大量观测,留下了很多新奇而有趣的宝贵资料.其实,它的本体只是冰-尘冻结的小彗核,随着走近太阳而蒸发的物质形成大而亮的彗发和长长的彗尾.

There is few opportunity, for a naked eye to see a comet, especially a bright comet tail. It is important to research it. Undoubtedly, the comet ISON is the most novel astronomical phenomena in 2013. It comes for the first time from the edge to the inner area of the solar system, and is discovered as a"new"comet, speculated that as near the earth it may show"century comet"outline of the spectacular through outer high temperature atmosphere of the sun (solar corona) and show its destruction face as" aflying moth darts into thefire". Many amateurs, experts as well as spacecrafts made a large number of observations, presented a lot of valuable information, novel and interesting. In fact, it''s ontology is freezing ice-dust small nucleus, with closing to the sun, the evaporation materials out of the nucleus form a big and bright coma and a long tail.
