陨石撞击挪威北部似原子弹爆炸

  据挪威《晚邮报》10日报道,当地时间6月7日凌晨,一枚陨石拖着浓烟坠毁在了挪威北部的一座山腰上,刹那间地动山摇,位于挪威卡拉斯约克的地球物理学和地震研究站都监控到了强烈的地震波。据专家称,这枚陨石可能是有史记载撞中挪威的最大一颗陨石,它撞击所产生的能量就如同一颗原子弹发生了爆炸!

 

陨石撞地惊天巨响

  据报道,当地时间7日凌晨2时05分,挪威特罗姆斯县北部地区的居民仰望夜空时,看到一个明亮的火球划过天空,几分钟后,他们就听到远处传来一声惊天动地的巨响,仿佛发生了大爆炸。

  当地一座农场的主人彼得·布鲁沃德当时正拿着一个照相机在农场中转悠,因为他的一只母马就要生小马驹了。彼得抬头时,正好看到一颗陨星划过夜空,他立即用照相机将那颗火球拍摄了下来。彼得说:“我看到天空中划过了一道明亮的火光,这是一道拖着烟雾尾巴的亮光。”

  彼得拍下陨石划过夜空的照片后,就开始继续照料他的农场牲畜,就在这时,他听到了陨石撞地产生的巨响。彼得说:“我就听到了陨石撞击地面的巨响,那声音听起来就像一公里远的地方引爆了一个炸药库一样。”

撞中山腹无人伤亡

  这颗撞地陨石同样让天文学家们感到兴奋,事实上凌晨2时13分,位于挪威卡拉斯约克的地球物理学和地震研究站也监控到了陨石撞地产生的巨大声响和随后引发的地震波。

  挪威著名天文学家克努特说,挪威的夏季夜空非常明亮,当这颗陨石划过夜空时,方圆几百公里范围内的居民都能够看到它,这颗陨石后来撞到了一座无人山腰上,到目前为止,尚没有伤亡报道。

威力巨大创下纪录

  科学家相信,这颗陨石的撞击能量和广岛原子弹爆炸差不多。克努特说:“这真是太不同寻常了,我无法想象在现代挪威历史上,竟然还会发生这样强大的陨石撞击事件。这颗陨石撞击所产生的能量,就如同一颗原子弹爆炸。当然陨石不具有辐射性,但它的爆炸威力,我们完全可以拿它和广岛原子弹比较。”

  天文学家相信,这颗陨石可能是有史记载撞中挪威的最大一颗陨石。克努特说:“历史记录显示,1904年,阿尔塔陨石曾经撞中过挪威,但那颗陨石大约90公斤重,我们认为周三撞中挪威的陨石,体积和重量还要大得多。”克努特呼吁看到这颗陨石撞地或发现陨石残骸的居民,赶快和挪威天体物理学协会进行联系。沈志真编译

挪威《晚邮报》报道的原文:
Here's where the meteorite hit
Residents of the Norwegian county of Nord-Troms were shaken when a meteorite struck the valley of Reisadalen last week. Experts are debating its impact, but they've found the site where it hit the ground.

An astronomer at the University of Oslo, Knut J?rgen R?ed ?degaard, told Aftenposten.no last week that he thought the meteorite that was photographed streaking through the sky could have had the same impact as the atomic bomb that hit Hiroshima in 1945.

"Of course the meteorite is not radioactive, but in explosive force we may be able to compare it to the (atomic) bomb," R?ed ?degaard said.

Truls Lynne Hansen of the Northern Lights Observatory (Nordlysobservatoriet) in Troms? disputes R?ed ?degaard's description, calling it an exaggeration.

"Our atmosphere is peppered with small stones from outer space all the time," Hansen told newspaper Aftenposten. "Most burn up and disappear, but some land here."

He thinks that what hit northern Norway last week was a stone weighing around 12 kilos (about 26 pounds). "Out in space it generated enormous speed, but after entering our atmosphere its tempo eased," Hansen said. "This kind of meteorite isn't radioactive and it's not glowing when it hits the ground."

The meteorite, whatever its size, created a stir nonetheless. Norway's Defense Ministry tries to track all flying objects and be prepared via radar on land, at sea and in the air.

"We can observe such meteorites," said John Espen Lien of the northern military command in Bod?. "But everything happens so fast, and most of them disappear before they hit the ground."
