Today, the sun had a comet for breakfast. The icy visitor from the outer solar system appeared with no warning on April 9th and plunged into the sun during the early hours of April 10th. One comet went in, none came out. The Solar and Heliospheric Observatory (SOHO) had a good view of the encounter:
昨天（因为我发的文迟了一天），太阳把一颗彗星当早餐吃了。这个来自外太阳系的结满冰的来访者，在没有预兆的情况下在4月9日出现，并且在4月10日的凌晨时分(世界时UT)，冲进太阳，不过没有再出来了。太阳和太阳风层探测器清晰拍下这一情景：

The comet was probably a member of the Kreutz sungrazer family. Named after a 19th century German astronomer who studied them in detail, Kreutz sungrazers are fragments from the breakup of a giant comet at least 2000 years ago. Several of these fragments pass by the sun and disintegrate every day. Most are too small to see but occasionally a big fragment like today's attracts attention. 这是一颗克鲁兹族（Kreutz）掠日彗星，以19世纪德国的一位详细研究这个族的天文学家的姓氏来命名。克族彗星来源于一颗两千年前的巨大彗星的解体。每天都有一些碎片经过太阳，不过大部分都太小，以致难于观测到。偶然会出现像这个一样，引人注意。
This has been an active year for big, bright sungrazers. There was one on Jan. 4th, one on March 12th, and now one today. Normally we see no more than 3 or 4 bright ones in a whole year; now we're seeing them almost once a month. It could be a statistical fluctuation or, maybe, a swarm of Kreutz fragments is nearing perihelion (closest approach to the sun). Stay tuned for doomed comets! 今年是明亮的掠日彗星的活跃年。一月4日有一个，3月12日有一个，现在又有一个。正常情况下，一年最多出现3--4个亮彗星。现在我们几乎一个月内就看见他们一次。这可能是一个统计起伏，或者正有一大群克族碎片靠近近日点（最接近太阳的位置）。继续留意这命中注定的彗星吧~！
