A newly-discovered comet is plunging toward the sun and probably will not survive. The encounter is too close to the sun for human eyes to see, but the Solar and Heliospheric Observatory (SOHO) is able to monitor the action using an opaque disk to block the sun's glare.
The doomed comet is 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 this one--attracts attention.
一个新发现的彗星正在冲向太阳而且很可能不会幸存。他对于人眼来说距离太阳太近了,但是SOHO卫星能够利用一个不透明的圆盘挡住太阳的阳光显示出这次现象。
这个命运注定了的彗星可能是略日彗星族克鲁兹组的一员。由19世纪德国一个详细研究他的天文学家命名。克鲁兹族彗星是有一个巨大的彗星在2000多年前解题而成。每天有很多这些碎片经过太阳并被瓦解。大多数碎片都很小但偶尔也会有一个大的碎片会像这个一样引起注意。
